Full textAbstract:
Is there something special about group rights? Many would say "yes". For some, only certain kinds of groups--ones that are oppressed, or play a special role in well-being--may have rights. For others, the kind of group is not as important as the group's culture and internal structure. At the very least, many argue, group rights ought to be more restricted than individualistic ones. For these reasons, arguing the merits of a group right is often thought to require a theory of groups or of group identity. If only certain kinds of groups may have rights then one has to identify the roles that various groups and/or identities play in personal well-being. If a group's culture or internal structure must meet certain standards then one must develop a theory of how culture or the internal organization of a minority influences people. I argue that it is a mistake to think that arguing a group right requires a theory of groups. This mistake reflects a tendency to think about group membership as a kind of good and to focus on its internal, psychological significance. But if one thinks about group membership as a vehicle of action, and focuses on the concrete effects it may have, it becomes apparent that arguing for a group right does not require a theory of groups, group identity or culture. For in the end, the issues that one must address in arguing a group rights are issues about groups. Rather, they are issues about political and moral authority, and about the extent to which moral and political norms ought to recognize and reinforce the ways that people depend upon one another. These are important issues and they raise pressing questions for political philosophy. But they are not about groups.

Full textAbstract:
Part I of this thesis presents methods for finding the primitive permutation groups of degree d, where 2500 ≤ d < 4096, using the O'Nan-Scott Theorem and Aschbacher's theorem. Tables of the groups G are given for each O'Nan-Scott class. For the non-affine groups, additional information is given: the degree d of G, the shape of a stabiliser in G of the primitive action, the shape of the normaliser N in S[subscript(d)] of G and the rank of N. Part II presents a new algorithm NormaliserGL for computing the normaliser in GL[subscript(n)](q) of a group G ≤ GL[subscript(n)](q). The algorithm is implemented in the computational algebra system MAGMA and employs Aschbacher's theorem to break the problem into several cases. The attached CD contains the code for the algorithm as well as several test cases which demonstrate the improvement over MAGMA's existing algorithm.

Full textAbstract:
In this thesis we study Kähler groups and their connections to Geometric Group Theory. This work presents substantial progress on three central questions in the field: (1) Which subgroups of direct products of surface groups are Kähler? (2) Which Kähler groups admit a classifying space with finite (n-1)-skeleton but no classifying space with finitely many n-cells? (3) Is it possible to give explicit finite presentations for any of the groups constructed in response to Question 2? Question 1 was raised by Delzant and Gromov. Question 2 is intimately related to Question 1: the non-trivial examples of Kähler subgroups of direct products of surface groups never admit a classifying space with finite skeleton. The only known source of non-trivial examples for Questions 1 and 2 are fundamental groups of fibres of holomorphic maps from a direct product of closed surfaces onto an elliptic curve; the first such construction is due to Dimca, Papadima and Suciu. Question 3 was posed by Suciu in the context of these examples. In this thesis we: provide the first constraints on Kähler subdirect products of surface groups (<strong>Theorem 7.3.1</strong>); develop new construction methods for Kähler groups from maps onto higher-dimensional complex tori (<strong>Section 6.1</strong>); apply these methods to obtain irreducible examples of Kähler subgroups of direct products of surface groups which arise from maps onto higher-dimensional tori and use them to show that our conditions in Theorem 7.3.1 are minimal (<strong>Theorem A</strong>); apply our construction methods to produce irreducible examples of Kähler groups that (i) have a classifying space with finite (n-1)-skeleton but no classifying space with finite n-skeleton and (ii) do not have a subgroup of finite index which embeds in a direct product of surface groups (<strong>Theorem 8.3.1</strong>); provide a new proof of Biswas, Mj and Pancholi's generalisation of Dimca, Papadima and Suciu's construction to more general maps onto elliptic curves (<strong>Theorem 4.3.2</strong>) and introduce invariants that distinguish many of the groups obtained from this construction (<strong>Theorem 4.6.2</strong>); and, construct explicit finite presentations for Dimca, Papadima and Suciu's groups thereby answering Question 3 (<strong>Theorem 5.4.4)</strong>).

The thesis centres around two problems in the enumeration of p-groups. Define f<sub>φ</sub>(p<sup>m</sup>) to be the number of (isomorphism classes of) groups of order p<sup>m</sup> in an isoclinism class φ. We give bounds for this function as φ is fixed and m varies and as m is fixed and φ varies. In the course of obtaining these bounds, we prove the following result. We say a group is reduced if it has no non-trivial abelian direct factors. Then the rank of the centre Z(P) and the rank of the derived factor group P|P' of a reduced p-group P are bounded in terms of the orders of P|Z(P)P' and P'∩Z(P). A long standing conjecture of Charles C. Sims states that the number of groups of order p<sup>m</sup> is<br/> p<sup><sup>2</sup>andfrasl;<sub>27</sub>m<sup>3</sup>+O(m<sup>2</sup>)</sup>. (1) We show that the number of groups of nilpotency class at most 3 and order p<sup>m</sup> satisfies (1). We prove a similar result concerning the number of graded Lie rings of order p<sup>m</sup> generated by their first grading.

Full textAbstract:
The Atiyah Conjecture originates from a paper written 40 years ago by Sir Michael Atiyah,
a famous mathematician and Fields medalist. Since publication of the paper, mathematicians
have been working to solve many questions related to the conjecture, but it is still open.
The conjecture is about certain topological invariants attached to a group G. There are
examples showing that the conjecture does not hold in general. These examples involve
something like the lamplighter group. We are interested in
looking at examples where this is not the case. We are interested in the specific case where
G is a finitely generated group in which the Pr'ufer group can be embedded as the center.
The Pr'ufer group is a p-group for some prime p and its finite subgroups have unbounded
order, in particular the finite subgroups of G will have unbounded order.
To understand whether any form of the Atiyah conjecture is true for G, it will first help to
determine whether the group ring kG of the group G has a classical ring of quotients for
some field k. To determine this we will need to know the zero divisors for the group ring
kG. Our investigations will be divided into two cases, namely when the characteristic of the
field k is the same as the prime p for the Pr'ufer group and when it is different.<br>Master of Science

Full textAbstract:
The present thesis aims to develop an analogy between the methods for recognizing a black box group and the classification of the finite simple groups. We propose a uniform approach for recognizing simple groups of Lie type which can be viewed as the computational version of the classification of the finite simple groups. Similar to the inductive argument on centralizers of involutions which plays a crucial role in the classification project, our approach is based on a recursive construction of the centralizers of involutions in black box groups. We present an algorithm which constructs a long root SL_2(q)-subgroup in a finite simple group of Lie type of odd characteristic $p$ extended possibly by a p-group. Following this construction, we take the Aschbacher'<br>s ``Classical Involution Theorem'<br>'<br>as a model in the final recognition algorithm and we propose an algorithm which constructs all root SL_2(q)-subgroups corresponding to the nodes in the extended Dynkin diagram, that is, our approach is the construction of the the extended Curtis - Phan - Tits presentation of the finite simple groups of Lie type of odd characteristic which further yields the construction of all subsystem subgroups which can be read from the extended Dynkin diagram. In this thesis, we present this algorithm for the groups PSL_n(q) and PSU_n(q). We also present an algorithm which determines whether the p-core (or ``unipotent radical'<br>'<br>) O_p(G) of a black box group G is trivial or not where G/O_p(G) is a finite simple classical group of Lie type of odd characteristic p answering a well-known question of Babai and Shalev.
The algorithms presented in this thesis have been implemented extensively in the computer algebra system GAP.

Full textAbstract:
The purpose of this study is to examine how body language, specifically handgestures, correlate to in-group and out-group notions. To approach the issue thehand gestures of two politicians are compared with a focus on how theirgestures relate to in-group and out-group notions in their speech. Interactionanalysis is applied, and the gestures of each politician are categorised andsummarised to be analysed. The analysis reveals that there is a distinctdifference between the two politicians in what gestures they use over all, andconsequently also differences in their gestures when discussing in-groups versusout-groups. However, the main takeaway from the discussion is that one of thepoliticians is directing their gestures towards the camera, whereas the otherpolitician mostly directs their gestures at the live audience.

Full textAbstract:
Educational Psychology<br>Ph.D.<br>Matching relations identified by Herrnstein (1961) demonstrate behavior rates as a function of the ratio of reinforcement rates for alternative behaviors. The mathematical relationship identified by Herrnstein and modified by Baum (1974) was later applied to foraging animals, given the option of two patches (Kennedy & Gray, 1993). This application lead to the demonstration that animals (Baum & Kraft, 1998) and humans (Kraft & Baum, 2001) will engage in emergent group behavior that is distinct from individual matching relations. To more completely understand group matching in humans, group relations beyond foraging must be investigated. This study expands on the findings of Kraft and Baum (2001) and subsequent studies by introducing a group contingency for point earnings. Using an ABAB/BABA experimental design, interdependent group contingency was compared to individual contingency in two experimental sessions with different sets of participants. To better understand individual performance in matching rations, a temporal discounting measure was administered to participants (Beck & Triplett, 2009). Scores were transformed into area-under-the-curve values and correlated with total points earned. Participants were divided into teams based on their scores on a measure of temporal discounting with which they earned points during the group contingency conditions. An effect for group contingency was found for Experiment 2 but not Experiment 1. Order effects apparent in the data from both experiments are attributed to the BABA design used in Experiment 2. Results across the two experiments show a relationship between temporal discounting scores and total points earned for participants with valid temporal discounting scores (n = 13). Future research should expand upon these findings in applied contexts.<br>Temple University--Theses

For this system of objects, we can show that, to some extent, the choice of the function j is not critical, for it can be ???absorbed??? into the function e. Also, when K is compact, we can show that ??? ker ?? = { f ?? E : ???k f (???g) dg = 0}. These results turn out to be very useful for calculations on s2 ??? G/H, where G = SO(3) and H???

Moreover, we can show that there is more than one solution for the case where s, E and E# are as chosen by Rouviere, if e is does not have to satisfy e(??,??) = e(??,??).

Full textAbstract:
Intragroup conflict research has shown task and relationship conflict have different effects on group outcomes, and suggests groups promote task conflict while avoiding relationship conflict. However, these suggestions have not yet been tested. This study examines the moderating role of group conflict handling on conflict type-group outcome relationships. Results of a field survey of 96 business school project groups showed task conflict inhibited performance when groups used avoidance tactics; however, these effects were negated when avoidance tactics were not used. Similarly, relationship conflict was only harmful to performance when avoided. When the use of avoidance was low, relationship conflict improved performance. Collaboration mitigated the harmful effects of task conflict and compromising mitigated those of relationship conflict on group satisfaction. Results from this work provide an important first look at how group conflict handling behaviors moderate the relationships between conflict types and group outcomes.

Part I of this thesis studies P[subscript(G)](d), the probability of generating a nonabelian simple group G with d randomly chosen elements, and extends this idea to consider the conditional probability P[subscript(G,Soc(G))](d), the probability of generating an almost simple group G by d randomly chosen elements, given that they project onto a generating set of G/Soc(G). In particular we show that for a 2-generated almost simple group, P[subscript(G,Soc(G))](2) 53≥90, with equality if and only if G = A₆ or S₆. Furthermore P[subscript(G,Soc(G))](2) 9≥10 except for 30 almost simple groups G, and we specify this list and provide exact values for P[subscript(G,Soc(G))](2) in these cases. We conclude Part I by showing that for all almost simple groups P[subscript(G,Soc(G))](3)≥139/150. In Part II we consider a related notion. Given a probability ε, we wish to determine d[superscript(ε)] (G), the number of random elements needed to generate a finite group G with failure probabilty at most ε. A generalisation of a result of Lubotzky bounds d[superscript(ε)](G) in terms of l(G), the chief length of G, and d(G), the minimal number of generators needed to generate G. We obtain bounds on the chief length of permutation groups in terms of the degree n, and bounds on the chief length of completely reducible matrix groups in terms of the dimension and field size. Combining these with existing bounds on d(G), we obtain bounds on d[superscript(ε)] (G) for permutation groups and completely reducible matrix groups.

The second object of interest in the thesis is the Jacobi group, which we think of as being associated to a compact Riemann surface of genus one. A connection is made between the Jacobi group and a certain central extension of G§. Finally, we define a generalisation of the Jacobi group that may be thought of as being associated to a compact Riemann surface of genus g ≥ 1.

viii, 125 p. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number.<br>Finite p -groups are studied using bilinear methods which lead to using nonassociative rings. There are three main results, two which apply only to p -groups and the third which applies to all groups.
First, for finite p -groups P of class 2 and exponent p the following are invariants of fully refined central decompositions of P : the number of members in the decomposition, the multiset of orders of the members, and the multiset of orders of their centers. Unlike for direct product decompositions, Aut P is not always transitive on the set of fully refined central decompositions, and the number of orbits can in fact be any positive integer. The proofs use the standard semi-simple and radical structure of Jordan algebras. These algebras also produce useful criteria for a p -group to be centrally indecomposable.
In the second result, an algorithm is given to find a fully refined central decomposition of a finite p -group of class 2. The number of algebraic operations used by the algorithm is bounded by a polynomial in the log of the size of the group. The algorithm uses a Las Vegas probabilistic algorithm to compute the structure of a finite ring and the Las Vegas MeatAxe is also used. However, when p is small, the probabilistic methods can be replaced by deterministic polynomial-time algorithms.
The final result is a polynomial time algorithm which, given a group of permutations, matrices, or a polycyclic presentation; returns a Remak decomposition of the group: a fully refined direct decomposition. The method uses group varieties to reduce to the case of p -groups of class 2. Bilinear and ring theory methods are employed there to complete the process.<br>Adviser: William M. Kantor

Full textAbstract:
The primary purpose of this study is to investigate whether the effect of group identity on individuals' willingness to cooperate is moderated by benefit asymmetry (i.e., mutual cooperation may benefit some group members more than others). I conduct an experiment in which participants act as group members for a hypothetical company. Consistent with expectations, I find that a strong group identity promotes employees' cooperation rates, but only in situations in which benefits resulting from mutual cooperation are symmetric. When the benefits are asymmetric, employees' willingness to cooperate depends on whether they are disadvantaged or advantaged as well as the level of group identity. Specifically, the disadvantaged employees are less likely to cooperate when group identity is high. In contrast, the advantaged ones' willingness to cooperate is unaffected by the level of group identity. Results of my study suggest that, in situations of benefit asymmetry, inducing a high level of group identity may have unintended negative consequences on group performance as well as organizational productivity.

The study of orderable groups is a topic that is all too often overlooked as a topic in algebra.
The subject of orderable groups is a field of study which is directly associated with algebraic group theory, algebraic topology, and set theory. This paper will act as a guide into the world of orderable groups. It begins by enlightening the reader to the fundamental axioms of orderable groups, as well as, noting various important groups on which orders are often considered. We will then consider more interesting groups, on which the placement of orders is considered less often.
After considering the orderings placed on various groups, we wish to consider in further detail the topologies of the sets of these orders. In particular, it is important to consider whether the set of orders placed on a particular group is finite or uncountable. We prove the latter by creating a homeomorphism from the group to the Cantor set, a set which is known for its uncountability.<br>Master of Science

Full textAbstract:
The nonconscious processing of the mind is a prevalently studied body of research in the social psychology literature. The central focus assesses how priming of stimuli is able to activate trait concepts within the mind thus leading to cognitive and behavioral changes outside of the individuals' awareness or intent. Unfortunately, management scholars have failed to use this methodology to study organizational phenomenon. As such, it is the purpose of this research to apply a nonconscious thought processing lens to one of management's most studied areas, group processes. This dissertation proposes a model that accounts for the influence of priming on group processes. We conducted two studies measuring expectations regarding a specific work group (Study 1) and perceptions of group processes and performance on a group task (Study 2). To accomplish this, we utilized two priming techniques: subliminal (Study 1) and mindful (Study 2) to assess the influence of these nonconscious processes. In order to test our model, we used ANOVAs (Study 1) and ANCOVAs (Study 2) to measure the impact of priming on our dependent measures. We found the predicted results that priming is able to directly influence both expectations about groups and various group processes (i.e. group cohesion, group credibility, group coordination, and perceived loafing) during the performance of an actual group task as well as group performance (i.e. actual group behavior). Such results provide initial evidence that nonconscious processes can influence the expectations and performance of individual's to be more productive while working in groups. Most importantly, these results show that these changes can be made without the individual's awareness. Theoretically, these results provide additional support for organizational behavior scholars to include more nonconscious thought processing components in their current models. Future research should focus on the experiences individuals have with groups and how they can be used to shape the beliefs systems and subsequent behaviors when performing in groups. In other words, do individuals with positive past experiences inherently perform better, and prefer to work, in groups in the future?

ABSTRACT
GROUP LEADERSHIP OF EXPERIENCED MIDDLE SCHOOL COUNSLEORS
by
Robert E. Rice
Middle school students experience biological, cognitive, and social changes as they struggle with identity formation, self-concept, self-esteem, and academic success. Psycho-educational groups are an effective and efficient method for confronting social/emotional or academic problems that prohibit middle school students from performing well in schools. An essential component in the successful counseling of middle school groups is the skill and experience of the group leader. Research on school-based groups has focused on all areas with the exception of group leadership. Therefore, the purpose of this study is to explore how experienced middle school group leaders approach and conduct psycho-educational groups. This qualitative study uses a grounded theory methodology to investigate the practices, experiences, and perceptions of fourteen middle school counselors. The theory that emerged is grounded in the data from the participants and represents how they were able to conduct small groups in schools despite barriers many other school counselors experienced. Through educational leadership, relationship building, and an understanding of the systems at work in schools, these participants were able to establish a group program in their schools. The participants in this study also reveal the experiences they used to develop their skills as group leaders. The results of this study may have important implications to middle school counselors, researchers, and counselor educators in understanding the group and educational leadership skills needed to conduct effective groups in a middle school setting.

Full textAbstract:
The study aimed to identify and understand the phenomenon of group processes comparing two Personal Development (PD) group modalities. One group mainly used verbalisation and the other mainly used movement for interaction and self-expression. Group processes were expressed through the analysis of the participant's non-verbal movements and the verbal expressions of their experience in the group. The thesis of this study was that group processes can be expressed and identified through movement and verbal expressions. This study built on previous studies that have explored group processes in both Dance Movement Psychotherapy (DMP) and in Verbal Group Psychotherapy fields in relation to PD groups. Two theoretical frameworks that underpinned this study were: DMP as group work and Group Psychotherapy with the primary focus on group processes in PD groups. These theories were selected for their pertinence to the understanding of group processes and PD groups. The comparison between the groups intended to answer the study's question: which group processes as expressed verbally and non-verbally in movement can be identified in a dance movement PD group compared with a verbal PD group? Qualitative hermeneutic phenomenology methodology was employed in this study in order to answer the above question using two collection and analysis methods: movement observation using Laban Movement Analysis (LMA) and a thematic analysis of participants' verbal reflections in semi-structured interviews. The findings of the study have shown which group process developed in each of the PD groups identified through the two collections methods. For instance, they were conflict, rivalry, trust, intimacy and cohesion. The analysis of the DM PD group has shown differences in findings between that which the movement observation identified and that which participants described in the interviews. The study aimed to contribute to the body of knowledge regarding group processes in DMP and group psychotherapy theory and research. Exploring group processes through the use of movement and verbalisation adds to the professional development and training in both fields. The study outcome offers an original contribution to practice, through the development of a group work guide for facilitators, derived from the group processes conceptual model. It represents a new way of understanding group processes and dynamics through the observation of a group's movements and verbal reflections by participants. This guide is aimed at supporting facilitators of PD groups when considering interventions both when leading groups and when reflecting on the groups' processes.

Roughly speaking, a group G is omnipotent if orders of finitely many elements can be controlled independently in some finite quotients of G. We proved that pi1(S) is omnipotent when S is a surface other than P2,T2 or K2 . This generalizes the fact, previously known, that free groups are omnipotent. The proofs primarily utilize geometric techniques involving graphs of spaces with the aim of retracting certain spaces onto graphs.<br>Approximativement, on peut dire qu'un groupe G est omnipotent si les ordresquantité d'élements d'une quantite finie d'elements peuvent etre controles independamment dans unquotient fini de Nous avons prouve que 7Ti(5) est omnipotent quand S estune surface autre que P2, T2 ou K2.

The aim of this study was to explore, from a group dynamics perspective, the adult learners' experiences in a learnership program structured to include employed and unemployed learners. A secondary aim was to develop guidelines for practitioners regarding the implementation of learnerships that are structured to include employed and unemployed learners, taking into account the group dynamics at play. The case study played out within a pharmaceutical distribution company within South Africa. A qualitative, constructivist grounded theory method was used to analyse the data that were collected by means of questionnaires and focus groups. The data collected were transcribed and uploaded into Atlas.ti, which is a visual qualitative data analysis and theorybuilding software program that contributes to the management of qualitative data. It was used to complete a rigorous inductive-abductive analysis. The final code list contained 277 codes linked to 29 code families which in turn were linked to 8 super families. These super families were described and the experiences of the learners were then interpreted by means of a number of group dynamics theories and adult learning theories that were discussed in the preceding literature chapters. In the case study the exploration of the learners' experience indicated that certain group dynamics were not taken into consideration and this led to an emotionally burdened experience. If one considers the adult learning theory, these experiences could influence the learning effectiveness. The implementation of a learnership program taking the group dynamics into consideration prior to implementation thereof, could contribute towards a more successful learnership. Guidelines were given based on the conclusions of the research for example: <ul> <li> Ensure that all the relevant parties including management, supervisors, employed learners, unemployed learners, employed staff, SETA etc. strive towards the same goal right from the start.</li> <li> Integrate the employed and unemployed learners' rights from the start so that the unemployed learners are accepted as part of the system.</li> <li> Make it very clear to the employed staff that the unemployed learners are not a threat to their employment within the company as the unemployed learners have not been given a commitment that they will be employed after the learnership.</li> <li> Make sure that the training facilitators are well trained and equipped to deal with the group dynamics that can develop in the classroom environment so that they can contribute to the containment of emotions and to alert the company of the events.</li> <li> Ensure that change agents are available to monitor and manage these group dynamics.</li> <li> Explain the differences and similarities that might exist between the groups and assist the groups to realise their mutually dependent relationship.</li> </ul> The guidelines obtained from this study can be used to stimulate the thinking process when planning and managing the implementation of a learnership program in order to be aware of consequential implications that group dynamics can have on the successful implementation of such a learning program. The conclusions and guidelines will be useful to human resources practitioners, training providers and line managers that are planning to implement similar learnership programs. AFRIKAANS: Die doel van die studie was om volwasse leerders betrokke by ‘n leerlingskapprogram wat gestruktureer is om bestaande werkers en werklose leerders in te sluit, se ervaring vanuit ‘n groepdinamika perspektief te ondersoek. ‘n Sekondêre doelwit was om riglyne te ontwikkel vir mense in die praktyk met betrekking tot die implementering van ‘n leerlingskapprogram vir volwasse leerders bestaande uit werklose leerders en leerders in diens van ‘n bepaalde maatskappy, met in agneming van die groepdinamika daarby betrokke. Die gevallestudie het plaasgevind binne ‘n farmaseutiese verspreidingsmaatskappy in Suid-Afrika. ‘n Kwalitatiewe, konstruktiwistiese metode is gebruik om die data te analiseer wat deur vraelyste en fokusgroepe versamel is. Die data is getranskribeer en ingelees in Atlas.ti, wat ‘n visuele kwalitatiewe data-analise en teoretiese gebaseerde sagtewareprogram is wat bydra tot die bestuur van kwalitatiewe data. Hierdie program is gebruik om ‘n indringende gebaseerde teorieanalise te doen. Die finale kodelys bestaan uit 277 kodes gekoppel aan 29 kode families wat weer op hul beurt gekoppel is aan 8 hooffamilies. Hierdie hooffamilies is beskryf en die navorsingsgebeure van die studie is by wyse van groepdinamikateorieë en volwasseleerteorieë (wat in die vorige literatuur hoofstukke van die studie bespreek is) geïnterpreteer. In hierdie gevallestudie het die interpretasie van die ervarings van die leerders wat ondersoek is, daarop gewys dat sekere groepdinamika nie oorweeg is nie en dat dit gelei het tot ‘n emosionele stresvolle ervaring. Volwasseleerteorie dui aan dat hierdie ervarings die leereffektiwiteit kon beïnvloed het. Die implementering van ‘n leerlingskap program waar die groepdinamika in ag geneem word voor die implementering kan bydra tot die sukses van soortgelyke leerlingskapprogramme. Die riglyne wat deur hierdie studie verkry is, kan gebruik word om die denkproses te stimuleer tydens die beplanning en die bestuur van die implementering van soortgelyke leerlingskapprogramme. Dit sal veroorsaak dat die betrokke persone bewus is van die invloed van groepdinamika kan hê met betrekking tot die suksesvolle implementering van ‘n leerlingskap program. Die navorsingsinligting wat ingewin is, sal bruikbaar wees vir menslike hulpbronne praktisyne, opleidingsvoorsieners en lynbestuurders wat beplan om ‘n soortgelyke leerlingskapprogram te implementeer.

Full textAbstract:
In questa tesi vengono presentati alcuni risultati parziali riguardo la surface group conjecture di Melnikov.
La congettura è che ogni gruppo ereditariamente ad un relatore, residualmente finito, non libero e non ciclico sia un surface group.
Un surface group è un gruppo isomorfo al gruppo fondamentale di una superficie chiusa. Un surface group ammette una presentazione con una sola relazione ed ogni suo sottogruppo di indice finito è ancora un surface group e quindi un gruppo ad una sola relazione.
Chiameremo gruppi ereditariamente ad un relatore quei gruppi ad un relatore con la proprietà che ogni sottogruppo di indice finito sia ancora un gruppo ad un relatore.
I surface group hanno dimensione comologica 2 e sono gruppi di dualità. Baumslag ha dimostrato che i surface group sono residualmente finiti.
Un primo approccio ad una soluzione del problema è di tipo combinatorico. Alcune proprietà dei gruppi ad un relatore sono determinate da proprietà della relazione. Per esempio, un gruppo ad un relatore è privo di torsione se e solo se la relazione non è una potenza.
Un risultato combinatorio più utile e profondo è il Teorema di Identità di Lyndon, che si può dimostrare tramite il calcolo differenziale libero. Se un gruppo ad un relatore è non libero, privo di torsione e liberamente indecomponibile, allora è un gruppo di dualità. Inoltre il Teorema di Identità permette di determinare la struttura del modulo dualizzante.
Dopo questi risultati combinatori, si procede ad analizzare i gruppi ereditariamente ad un relatore utilizzando un risultato dovuto a Bieri et al, che hanno dimostrato come i gruppi di Poincaré di dimensione due sono surface groups.
Dato un gruppo di dualità ad un relatore G risulta essere un quoziente di ZG e si ha un sollevamento della mappa di augmentazione di ZG ad una mappa dal modulo dualizzante a Z se e solo se la relazione che definisce G è un commutatore.
Se il nucleo K di questo sollevamento è banale allora il modulo dualizzante è isomorfo a Z e G è un surface group, per cui K può essere visto come una misura di quanto G sia lontano dall'essere un surface group.
Le ipotesi della surface group conjecture hanno notevoli somiglianze ad alcune proprietà dei gruppi di Demushki, che sono gruppi pro-p ad un relatore e gruppi di dualità di Poincaré. La classificazione dei gruppi di Demushkin dovuta a Labue mostra che essi ammettono una presentazione (come pro-p gruppi) simile alla presentazione dei surface group. Si è quindi deciso di esplorare la possibilità di una relazione tra le due situazioni.
Dato un gruppo G che soddisfi le ipotesi della surface group conjecture e la cui unica relazione sia un commutatore, si procede a prenderne il completamento pro-p e se ne studia la struttura. Dato che i surface group sono residualmente liberi richiediamo anche che G sia residualmente libero. Dimostriamo quindi che G è p-buono, cioé che il morfismo naturale tra G e il suo completamento induce un isomorfismo tra i rispettivi gruppi di coomologia. Usiamo questa proprietà per caratterizzare il completamento pro-p di G.
Teorema. Sia G un gruppo ereditariamente ad un relatore, residualmente finito, non libero e non ciclico, la cui unica relazione sia un commutatore. Allora il completamento pro-p di G è un gruppo di Demushkin orientabile e quindi coincide con il completamento pro-p di un surface group.
Utilizzando la classificazione di Labute concludiamo che G deve avere un numero pari di generatori e che la relazione non può trovarsi nel secondo gruppo derivato del gruppo libero il cui quoziente offre la presentazione ad un relatore di G.
Inoltre, se G ha solo due generatori abbiamo una risposta positiva alla congettura.
