Full textIn this thesis we extend further the foundations of derived C-analytic geometry proposed by J. Lurie in DAG IX. Moreover, we show that his ideas can be used to develop a theory of derived non-archimdean spaces. Motivations are coming from nonabelian Hodge theory and from mirror symmetry. Among the main results there are generalizations of Grauert theorem and GAGA theorems for derived analytic stacks (including C-analytic orbifolds and analytic analogues of Artin stacks). We extensively study analytic deformation theory, including the analytic cotangent complex and its basic properties. Finally, we obtain an analytic version of Lurie's representability theorem. We use the language of infinity categories throughout the whole thesis
Fromenteau, Clément. "Sur le champ de Teichmüller des surfaces de Hopf." Thesis, Angers, 2017. http://www.theses.fr/2017ANGE0094.
Full textThe goal of this phd thesis is to use stacks to study Teichmüller spaces in an analytic framework. Kodaira Spencer theory of infinitesimal deformations is not enough to describe teichmüller space as a global analytic object. Stack theory is very well adapted tostuying moduli spaces and quotients. however it is essentially developped in an algebraic context. We adapt this theory to an analytic framework and we use it on simple but interesting example of Hopf surfaces. In particular we give two concrete atlases of the Teichmüller stack of Hopf surfaces. We compute some of its homotopy groups and homology groups. Finally we give some applications to homotopy classes of deformations of Hopf surfaces

Full textThe first two chapters review the necessary notions concerning nilpotent Lie algebras, and invariant differential operators. An overview of the existing results of Fujiwara, Corwin-Greenleaf & al. Related to the Duflo conjecture is given in details. The Kontsevich formulation of Deformation Quantization is also reviewed. The generalization for coisotropic submanifolds due to Cattaneo-Felder is also covered and the notion of the reduction algebra is defined. In the third chapter considering a nonzero character of a fixed Lie subalgebra of a general Lie algebra, we prove a Theorem stating that the reduction algebra of the affine space is isomorphic to a deformation of the algebra of invariant differential operators. An explicit formula of this isomorphism is given. Other reduction algebras are examined, and the relations between them and their specializations is described in details. In the forth chapter we calculate characters of the reduction algebra and its specialization thanks to triquantization diagrams and we give an explicit formula for this character. Using double induction, we prove that this character equals the character constructed with the Penney eigendistribution Finally we compute in full detail all the formulas introduced in the text for a 5-dimensional nilpotent Lie algebra. It is shown that the character formula obtained gives an isomorphism between reduction algebras containing the exponential of a differential operator of degree 3 with rational coefficients

Full textThis thesis presents a study of the motion of the Galilean satellites by analytical method. The solution gives the inequalities of the motion in the form of quasi-periodic of time. In chapter 1, we introduce the adopted method. The non-singular variables used in this work are simple expressions of the orbital elements. They facilitate the study of the long period evolution of the orbits of the system. The method gives, in the first stage, an intermediary solution supplied by the integration of all the terms which depend on time explicitly, and in the second stage, a variational solution which takes into account the free eccentricities and the free inclinations of the orbits. In chapter 2, we develop the perturbation function and the second member of the motion’s equations. The considered perturbation function arises from three actions : the interaction between the satellites, the action of the equatorial bulge of Jupiter and the Sun’s action. In chapter 3, we expose the different treatments used in the resolution of the equations and give some extracts from the most significant results ; in particular, the contributions to the high orders of the intermediary solution, a new solution of the libration’s equation, the first approximation of the variational solution and the terms of high degrees of eccentricities and inclinations, among which de Haerdtl’s inequalities are given with supplementary terms. In chapter 4, we present the calculation of the inequalities due to solar perturbations. This chapter contains, in the first part, a comparison of the results obtained with those of known theories, and in the second part the development of a new theory of the four great planets. The theory of Jupiter will be used as a jovicentric solar theory for the calculation of the perturbation of the Sun upon the Galilean satellites

Full textThe thesis examines the epistemological foundations of analytical positivism, i. E. The internal and logical coherence of analytical legal positivism. Analytical legal positivism insists on the separation of law and morality and on the social sources of law. At the same time, according to this theory, a particular importance and emphasis should be given to the study of legal concepts and language. After a systematization of the components (both methodological and substantive) of this theory, the thesis identifies its internal inconsistencies and tries to reconstruct the theory of meaning of legal statements according to an extended interpretation of the presuppositions of analytical legal positivism. This reconstruction cannot offer an adequate solution to the problems of this theory: the social sources thesis of law is methodologically implausible and is not compatible with the normativity thesis of legal positivism, that insists on the normative character of law. Consequently, the thesis stetches an alternative theory of law and suggests that the sources of law are pre-institutional and that the meaning of legal statements is also pre-conventional and referential

Full textAnalytic combinatorics is concerned with the study of combinatorial structures based on their generating functions, and also the efficient random generation of these structures using the Boltzmann method. The aim of this thesis is to analyze combinatorial structures generated by rational and algebraic grammars through a systematic study of the associated generating functions. The first part is dedicated to the study of the limit distributions of patterns in words generated by automata (rational grammars) and associated generating functions ℕrat: The resulting distribution is Gaussian when the automaton is strongly connected. We illustrate this phenomenon for the model of urban segregation due to the economist Schelling. We then give the first major result of this thesis: when the automaton is not strongly connected, it exhibits a wide variety of possible distributions. Then, we use these distributions for uniform random generation with two parameters (bivariate Boltzmann) and to "reverse engineer" certain empirical distributions arising in biology. The second part is dedicated to the asymptotic behavior generating functions ℕalg defined using algebraic grammars. According to the theorem of Drmota, Lalley, and Woods, these series have a square root behavior in their dominant singularity when the associated grammar is strongly connected. The second major result of this thesis characterizes all possible behaviors when the grammar is not strongly connected (these behaviors are related to dyadic numbers; we illustrate this fact constructively using grammars that generate multicolored trees). Then, we give some closure properties for the radius of convergence of these generating functions. Through these new characterizations, we can establish that various combinatorial objects, such as families of planar maps and random walks, cannot be generated by non-ambiguous algebraic grammars. The last part is dedicated to the random generation of combinatorial objects using an extension of the Boltzmann method in order to generate infinite objects, such as Galton–Watson trees with extinction probability p less than ½

Both Elster and Roemer think that game theory is very important to analyse the concepts of class interest, class consciousness exploitation and collective action not teleologically. Finally J.

Full textConsequently to the recent implementation of NPM-inspired reforms, cost accounting plays a key role in financing and governance of French hospitals. Calculating unit costs per hospital stay is indeed the first step in the elaboration of case-based tariffs. Moreover, unit costs are used to develop new management tools aimed at improving hospital efficiency. This study compared the current cost accounting method to an innovative activity-based one for the calculation of the unit costs of 2130 surgical procedures performed consecutively at the University Hospital of Montpellier in 2009. The results show a poor agreement between both methods. In addition, the current method fails to accurately reflect the real complexity of the management of patients in the operating room. New institutionalism suggests that the development of hospital cost accounting (a formal organizational structure) results from an isomorphic process by which health care institutions internalize the rationalized myth of unit cost calculation. In order to address the constraints and the complexity of reality, a certain degree of decoupling between the accounting and real activity occurs. Hence, cost accounting would not only be an efficiency improvement tool, but also a legitimating factor within a highly institutionalized environment. This raises the issue of the relevance of the tariffs and the management tools based on these unit costs

Full textIn this thesis we establish a gluing formula of real analytic torsion forms for flat vector bundles on a smooth fibration under certain assumptions. First, we obtain the gluing formula under assumption that a fiberwise Morse function exists. Second, we use the adiabatic method to prove the gluing formula in the case that the fiberwise twisted cohomology groupes of the fibration of cutting hypersurface vanish. In this thesis we assume that the metrics admit product structures near the cutting hypersurface. We also work on the asymptotic expansions of Bergman kernel

Full textThe failure of the mechanical parts is very often initiated by a surface defects. Consequently, the generation of compressive residual stresses on mechanical parts by introducing a heterogeneous plastic strain improves the resistance to fatigue and increases the lifetime of the parts. Among the processes making it possible to introduce residual stresses into the parts, the laser shock peening is more interesting for several reasons. On the one hand, it makes it possible to produce pressures on the surface of material of about 1 to 6 going GPa over short pulse times from 3 to 30 nanoseconds. In addition, he gives the opportunity of introducing residual stresses of compression on a certain depth while preserving the initial state of the treated part. The numerical simulation becomes necessary to determine the best physical phenomena involved. Thus, the semi-analytical method offers a lot of advantages, in particular the simplicity of the models and the computation times saving. This method was never extended to the dynamic problems. In this thesis the semi-analytical method was extended to the dynamic problems and the model implemented is applied for the simulation of the Laser process of shock

Full textThe non satisfaction stemming from classical perspectives on the use of accounting by managers is bound to (1) that they suffer from a lack of alignment onto the specificities of managerial work and to (2) that they seldom take into account the cognitive dimension of actors’ mental representations. That dissertation, in adopting a cognitive perspective, reports on a research about the roles of the accounting drivers in accordance with the manager’s expectations. Based simultaneously upon interviews with managers in several organisations (1st stage) and upon a case study of a large organisation (2nd stage), the research offers an analytical framework of the perception and the use of the accounting drivers. The literature review supplemented with the empirical study allows the construction of an integrative analysis grill of the roles devoted to accounting: information, decision making, relational and cognitive. Modes of rationality help reveal those meta-roles. These modes are substantial, procedural, partnerial and cognitive. Afterwards, cognitive issues were identified, that contribute to a better understanding of the behaviour of managers. Moreover light was shed on a large cognitive gap in between the manager and the accountant. Lastly, a taxonomy of managerial styles in the use of accounting drivers could stem from both empirical stages. Three ideal-types were stressed: a weak style (the detractor), a middle-range style (the opponent) and a strong style (the adept)

Full textIt is a reading of Keynes's work, attempting to take into account and throw light upon its epistemological and philosophical foundations. Beyond the dead-ends where the interpretation of the general theory as empirist or rationalist leads, the influences of both Moore and Russell enlighten the meaning of a treatise on probability. With his conception of probability, Keynes's analytical realism represents a chief contribution to these very authors' philosophy of knowledge. That philosophy of knowledge allows us to understand Keynes's conception of economics as a science which deals with organic and uses models. The issue is then to understand the message of the whole work and connections between a treatise on money and the general theory. A treatise on money appears as a scheme that has not been fully carried out. But, in the model Keynes outlines, the activity-level depends on the investment-volume. Consequently, the antithesis between a model presented in terms of periods and gravitation in a treatise on money, and a model based upon anticipations, which is the model of the general theory, seems of minor importance. Both converge on making more probable a proposition about economic reality

Full textIn order to explain Leibniz's theory of truth, the author chose to work according to a genealogical method. For each argument, even the most popular, the author tried to find the important moments of its creation, dating back to the texts of leibniz's youth. The genealogical method was also employed in an external way : the leibnizian fragments are confronted to older texts, the meaning of fundamental concepts is explained through the heritage of medieval and post-medieval scolastics. Throughout this approach, this work is the first ever devoted to leibniz logics in its integrality. It continuates what massimo mugnai already discovered about the logics of relations. The main arguments may be summarized this way : 1) Leibniz argues in favour of conceptualism. 2) This position implies a particular kind of ontologic engagement, in which consists mainly the suarezian heritage of leibnizian metaphysics. 3) One of the consequences of the conceptualism is the development of a intensional logics. This logics is not incompatible with the concept of class. 4) The intensional logics requires that an ontologic status be deserved to universals. 6) It has obliged leibniz to broaden the meaning of the fundamental logic relation, so that the inherence has become more and more a simple connexion. 7) The chapter 3 constitutes an attempt of evaluation of leibniz's ontology, which uses the tradition of the ontological square. It is demonstrated that leibniz meant to keep the two dimensions of ontology, while criticizing dramatically the notion of accident and profoundly modifying the fundamental relations of inherence and predication

Full textThis thesis concerns the pluripotential theory and equidistribution problems. It consists of 4 chapters. The first chapter is dedicated to the study of the regularity of the solution of the complexe Monge-Ampère equation on a compact Kahler manifold X. More precisely, using tools from the Cauchy-Riemann geometry, we prove that the last equation possesses a unique Holder continuous solution for a large geometric class of probability measures supported on real submanifolds of X. In the chapter 2, we study the intersecton of positive closed currents of higher bidegree. We prove there that the wedge product of two such currents one of which has a continuous superpotential est closed and positive. This property generalises a classical result for currents of bidegree (1,1). The next two chapters are applications of the pluripotential theory to equidistribution problems. In the chapter 3, we give an explicit speed of convergence for the equidistribution of Fekete's points in a compact subset K of the Euclidean space with piecewise smooth boundary toward the equilibrium measure of K. Here, the Fekete's points are good points for the interpolation problem of continuous functions by polynomials on K. A such control of speed is crucial in practice when ones use Fekete's points. The thesis is ended by the chapter 4 where we prove an analogue of Weyl's law for the resonances of a generic Schrodinger operator on an Euclidean space of odd dimension. The resonances are central objects in the research of Schrodinger operators. They play a similar role to that of eigenvalues in the compact setting

A parametrical study on the number of tubes, their diameter, the distance between the interfaces and their angular positions makes possible an interpretation of the physics useful to the design.
