Abstract:

Abstract In this paper we continue the study of powerfully nilpotent groups started in Traustason and Williams (J Algebra 522:80–100, 2019). These are powerful p-groups possessing a central series of a special kind. To each such group one can attach a powerful class that leads naturally to the notion of a powerful coclass and classification in terms of an ancestry tree. The focus here is on powerfully nilpotent groups of maximal powerful class but these can be seen as the analogs of groups of maximal class in the class of all finite p-groups. We show that for any given positive integer r and prime $$p>r$$p>r, there exists a powerfully nilpotent group of maximal powerful class and we analyse the structure of these groups. The construction uses the Lazard correspondence and thus we construct first a powerfully nilpotent Lie ring of maximal powerful class and then lift this to a corresponding group of maximal powerful class. We also develop the theory of powerfully nilpotent Lie rings that is analogous to the theory of powerfully nilpotent groups.

To each such group, one can attach a powerful nilpotency class that leads naturally to the notion of a powerful coclass and classification in terms of an ancestry tree. In this paper, we will give a full classification of powerfully nilpotent groups of rank 2. The classification will then be used to arrive at a precise formula for the number of powerfully nilpotent groups of rank 2 and order {p^{n}}. We will also give a detailed analysis of the ancestry tree for these groups. The second part of the paper is then devoted to a full classification of powerfully nilpotent groups of order up to {p^{6}}.

Abstract:

To assess among 3 groups differing in stress significance of differences in their scores on locus of control scales (Internal, Powerful Others, and Chance), 2 groups of college undergraduates (123 and 160 subjects) were tested. In both samples analysis indicated significant differences among the 3 groups in scores on the Powerful Others and Chance (external) scales, with the severely stressed group scoring higher than the milder stress groups. No significant differences were found on the Internality scale.

Abstract:

In this note we analyse the analogy between m-potent and p-central restricted Lie algebras and p-groups. For restricted Lie algebras the notion of m-potency has stronger implications than for p-groups (Theorem A). Every finite-dimensional restricted Lie algebra  is isomorphic to for some finite-dimensional p-central restricted Lie algebra (Proposition B). In particular, for restricted Lie algebras there does not hold an analogue of J.Buckley's theorem. For p odd one can characterise powerful restricted Lie algebras in terms of the cup product map in the same way as for finite p-groups (Theorem C). Moreover, the p-centrality of the finite-dimensional restricted Lie algebra  has a strong implication on the structure of the cohomology ring H•(,) (Theorem D).

Abstract:

While most of the literature on Islam over the past two decades has concentratedon the issue of Islamic resurgence, focusing mainly on the nature andworkings of political movements and militant Islamic groups, this book examinesinstead the beliefs and practices of ordinary Muslim, exploring an intricateweb of social relationships involving the 'ulama, government, Islamic institutions,Sufis, and the people Jiving in the rural and city areas of the country.The analysis demonstrates how in order to further our understanding ofMuslim society, we must gather fieldwork data on the relationship of the commonperson's Islamic practices to those of the Islamic tradition and apply therelevant analytical concepts to examine them. It further challenges the existingethnography of Muslim society which is not only based mainly on limitedempirical data but also conceals issues worthy of study and is, moreover, fullof assumptions oversimplifying the nature of the complex social relationshipsinvolved. For instance, anthropology implicitly assumes that the "native" is anaive and ignorant person who, as a corollary of this, is ignorant of his ownreligion. The consequence of this supposition has been that anthropologistswho have written on the subject have not found it necessary to examine howthe Islamic practices of the common people have been related to the Islamictradition.It was also often assumed that the Islamic knowledge of the 'ulama, and theirstatus as the learned ones, somehow separated them from the lives of the commonpeople. Only recently have researchers started studying the effect of theirfa tawa on society and people, little work having been done before on their livesand influence. This work refutes the assumption that the Islamic text is outsidesociety and that the 'ulama are an entity separate from the people.The author re-examines the view that different societies contain differentversions of Islam and points out that this type of thinking does not of itselfadvance our knowledge of the subject, nor does it offer a viable criteria for ...

In [Non-reidemeister knot theory and its applications in dynamical systems, geometry, and topology, preprint (2015), arXiv:1501.05208.] the first author gave the definition of [Formula: see text]-free braid groups [Formula: see text]. Here we establish connections between free braid groups, classical braid groups and free groups: we describe explicitly the homomorphism from (pure) braid group to [Formula: see text]-free braid groups for important cases [Formula: see text]. On the other hand, we construct a homomorphism from (a subgroup of) free braid groups to free groups. The relations established would allow one to construct new invariants of braids and to define new powerful and easily calculated complexities for classical braid groups.

Full text

Abstract:

Following the 2018 SEG Annual Meeting, the Gravity and Magnetics Committee held a postconvention workshop titled “Integrated imaging.” The half-day workshop attracted nearly 50 participants from various backgrounds. Three primary objectives of the workshop were to explore the nonseismic toolbox, highlight real examples of integrated projects that benefitted (or did not benefit) from nonseismic data, and provide geoscientists from all backgrounds a learning opportunity to see how they might optimize the value of their imaging projects via integration with relatively low-cost nonseismic methods. The workshop had a highly interactive format that differed from traditional presentation-based settings. After eight brief case studies were presented, three concurrent guided discussions ensued. Participants were divided into three groups, and each group focused on one discussion topic at a time. The groups rotated, allowing everyone to discuss all three topics. The first discussion was centered on two general questions: what is integrated imaging, and what tools are available for it? The second discussion provided an opportunity to examine the relationships between different physical properties that must be managed during integrated multiphysics analysis. The third discussion focused on the costs and benefits of a multiparameter data acquisition. According to feedback from participants, these discussions were the most valuable part of the workshop. The participants agreed that an integrated approach in geophysical data analysis is a powerful but currently undervalued tool. Also noted were the value of integration with nonseismic methods illustrated in the case studies and the need for the integrated approach in data analysis to be taught in schools in addition to the classic overview of individual geophysical methods.

Abstract:

AbstractThere is vast literature on secularism in India and on the effects of Hindu nationalism on secular constitutionalism. This article takes a different tack. It focuses on cases where minority status is contested or competing rights of minorities are at stake. The article uses three exemplary recent cases to illustrate how judicial doctrines devised to reform discriminatory religious practices or to protect minority interests have, perversely, favoured certain groups at the expense of others. In each area examined, the jurisprudence privileges the more powerful of those interests: the sanctity of Muslim personal law over the rights of Muslim women; Hindu dalits over dalits that converted to other religions; and minority educational institutions over children from ‘weaker’ and ‘disadvantaged’ sections of society. The article concludes by proposing a new jurisprudence of religion and constitutional practice for India, one that takes account of these inequalities and gives meaning to the fundamental rights of the most vulnerable individuals and groups.

Abstract:

49 paranormal healers working by laying-on of hands (direct healing) and healing at a distance were compared with 56 nurses and a control group of 73 randomly selected persons on their locus of control and especially on the subscale Powerful Others of Levenson. The paranormal healers scored external in locus of control, and their scores differed significantly from those of the other two groups tested on the Powerful Others subscale. This finding may be associated with the dependent position of paranormal healers since their profession is tolerated by medical doctors and the law.

Abstract:

By drawing on a selection of interviews from the website Engaged Philosophy, this paper highlights the work of philosopher-activists within their classrooms and communities. These philosophers have stepped out of the ivory towers and work directly with media, community and political groups, people in prison; or they encourage their students to engage in activist projects. The variety of approaches presented here shows the many ways philosophically inspired activism can give voice to those who are marginalized, shine a light on injustices, expose the root of social problems, and empower others to seek solutions. This work shows the relevance of philosophy to practical problems and the powerful effects it can have in the world.

Abstract:

The most powerful geometric tools are those of differential geometry, but to apply such techniques to finitely generated groups seems hopeless at first glance since the natural metric on a finitely generated group is discrete. However Gromov recognized that a group can metrically resemble a manifold in such a way that geometric results about that manifold carry over to the group [18, 20]. This resemblance is formalized in the concept of a ‘quasi-isometry’. This paper contributes to an ongoing program to understand which groups are quasi-isometric to which simply connected, homogeneous, Riemannian manifolds [15, 18, 20] by proving that any group quasi-isometric to H2×R is a finite extension of a cocompact lattice in Isom(H2×R) or Isom(SL˜(2, R)).

Abstract:

The theory of induced representations has served as a powerful tool in the computations of algebraicK-theory andL-theory ([2], [7], [4, 5], [9], [10, 11, 12, 13], [14], [17], [18]). In this paper we show how to apply this theory to obtain induction theorems for the higher Whitehead groups of Waldhausen. The same technique applies to the analogs of Whitehead groups in unitaryK-theory and inL-theory.For any ringAwith unit, letK(A) be the spectrum of the algebraicK-theory ofA([8, p. 343]). Given a discrete group Γ and a subringRof the rational numbers, Loday defines a map of spectra:*where (BΓ) is the classifying space of Γ union with a disjoint base point andRΓ is the group-ring of Γ overR.

Bestvina and Handel [1] have announced a powerful structure theorem for automorphisms of free groups that has as a consequence a proof of what has become known, to the amusement of Peter Scott, as the ‘so-called’ Scott Conjecture: if F is a free group of rank n and α:F→F is an automorphism, then Fix (α) = {w∈F|α(w) = w} has rank at most n.

Abstract:

We investigate the language classes recognized by group automata over matrix groups. For the case of 2 × 2 matrices, we prove that the corresponding group automata for rational matrix groups are more powerful than the corresponding group automata for integer matrix groups. Finite automata over some special matrix groups, such as the discrete Heisenberg group and the Baumslag-Solitar group are also examined. We also introduce the notion of time complexity for group automata and demonstrate some separations among related classes. The case of linear-time bounds is examined in detail throughout our repertory of matrix group automata.
