Abstract:
We identify and characterize mini-Bloch-sub-bands that condense out of the low-lying states in a semiconductor's conduction band due to repetitive patterns (as in an "antidot lattice"). We discuss limits on the validity of the tight-binding approximation. One appendix touches upon the complications (actually, simplification, in the case of silicon) when the dispersion is given by a set of anisotropic mass tensors, another treats the effects of cross-sectional shape on threshhold energy level of a conduit.

AbstractLet U/ℂ be a smooth quasi-projective variety of dimension d, CHr (U,m) Bloch's higher Chow group, andclr,m: CHr (U,m) ⊗ ℚ → homMHS (ℚ(0), H2r−m (U, ℚ(r)))the cycle class map. Beilinson once conjectured clr,m to be surjective [Be]; however, Jannsen was the first to find a counterexample in the case m = 1 [Ja1]. In this paper we study the image of clr,m in more detail (as well as at the “generic point” of U) in terms of kernels of Abel-Jacobi mappings. When r = m, we deduce from the Bloch-Kato conjecture (now a theorem) various results, in particular that the cokernel of clm,m at the generic point is the same for integral or rational coefficients.

Abstract:
Every theory of superconductivity can be disproved! This tongue-in-cheek theorem struck a chord when Felix Bloch announced it in the early 1930s. Virtually every major physicist then working on theory—including Bloch, Niels Bohr, Wolfgang Pauli, Werner Heisenberg, Lev Landau, Leon Brillouin, W. Elsasser, Yakov Frenkel, and Ralph Kronig—had tried and failed to explain the mysterious phenomenon in which below a few degrees kelvin certain metals and alloys lose all their electrical resistance. The frequency with which Bloch's theorem was quoted suggests the frustration of the many physicists who were struggling to explain superconductivity.Neither the tools nor the evidence were yet adequate for solving the problem. These would gradually be created during the 1940s and 1950s, but bringing them to bear on superconductivity and solving the long-standing riddle required a special set of talents and abilities: a deep understanding of quantum mechanics and solid-state physics, confidence in the solubility of the problem, intuition about the phenomenon, a practical approach to problem-solving, patience, teamwork, and above all refusal to give up in the face of repeated failures. When John Bardeen took on the problem of superconductivity in the late 1930s, he held it like a bulldog holds a piece of meat, until he, his student J. Robert Schrieffer, and postdoctoral candidate Leon Cooper solved it in 1957.

Abstract:
The study of the metamaterials and the phononic crystals is unavoidable for the development of innovative isolation techniques (acoustic, seismic or thermal) thanks to their control properties over the propagation of elastic waves at different wavelength scales. Making use of the spatial periodicity of such materials, it is possible to study the unit cell individually and only subsequently extending the type harmonic plane wave Solution of the equations of motion to the whole domain by applying the Floquet-Bloch theorem. In this thesis we study the dispersion curves obtained in the cases of one-dimensional and two-dimensional lattices through scripts in Matlab. Thus we obtain the characteristic band diagrams of the dispersion curves of these materials (pass band, stop band, bandgap and fano resonance). In particular, the present work focuses on the study of a lattice whose cells are tensegrity structures modeled as a reticular structure with the lamped mass approach: the study is reduced to the simplest case of two-dimensional monoatomic lattice. From the dynamic analysis of this model we obtain the dispersion curves of the pre-tension variation in the elements.

Abstract:
Cette thèse est consacrée à l'étude de trois problèmes d'hyperbolicité complexe et presque complexe. La première partie est dédiée à la recherche d'une conséquence quantitative de l'hyperbolicité au sens de Kobayashi, qui est une propriété qualitative. Le résultat obtenu prend la forme d'une inégalité isopérimétrique qui évoque l'inégalité d'Ahlfors relative aux recouvrements des surfaces de surfaces. Sa démonstration est purement riemannienne.La deuxième partie de la thèse est consacrée à la démonstration d'une version presque complexe du théorème de Borel, qui affirme que les courbes entières dans le plan projectif complexe évitant quatre droites en position générale sont linéairement dégénérées. Dans un plan projectif presque complexe, les J-droites substituent aux droites projectives et nous disposons d'un énoncé analogue pour les J-courbes entières. La démonstration de ce résultat repose sur l'utilisation de projections centrales et sur la théorie de recouvrement des surfaces d'Ahlfors.La dernière partie est consacrée à la démonstration d'une version presque complexe du théorème de Bloch, qui affirme qu'une suite non normale de disques holomorphes du plan projectif évitant quatre droites en position générale converge, en un certain sens, vers une réunion de trois droites. Notre résultat implique en particulier l'hyperbolicité du complémentaire dans le plan projectif presque complexe de quatre J-droites modulo trois J-droites
This thesis is dedicated to the study of three problems of complex and almost complex hyperbolicity. Its first part is dedicated to the research of a quantitative consequence to Kobayashi hyperbolicity, which is a qualitative property. The result we obtain has the form of an isoperimetric inequality that suggests Ahlfors' inequality, the central result of the theory of covering surfaces. Its proof uses only riemannian tools.The second part of the thesis is dedicated to the proof of an almost complex version of Borel's theorem, which says that an entire curve in the compex preojective plane missing four lines in general position is degenerate. In an almost compex context, we can obtain a similar result for entire J-curves just by replacing projective lines by J-lines. The proof of this result uses central projections and Ahlfors' theory of covering surfaces.The last part is dedicated to the proof of an almost complex version of Bloch's theorem, which says that given a sequence of holomorphic discs in the projective plane, either it is normal, either it converges in some sens to a reunion of three lines. Our result will show in particular that the complementary set of four J-lines in general position is hyperbolic modulo three J-lines

Abstract:
In this thesis we study gradings on blocks of group algebras. The motivation to study gradings on blocks of group algebras and their transfer via derived and stable equivalences originates from some of the most important open conjectures in representation theory, such as Broue’s abelian defect group conjecture. This conjecture predicts the existence of derived equivalences between categories of modules. Some attempts to prove Broue’s conjecture by lifting stable equivalences to derived equivalences highlight the importance of understanding the connection between transferring gradings via stable equivalences and transferring gradings via derived equivalences. The main idea that we use is the following. We start with an algebra which can be easily graded, and transfer this grading via derived or stable equivalence to another algebra which is not easily graded. We investigate the properties of the resulting grading. In the first chapter we list the background results that will be used in this thesis. In the second chapter we study gradings on Brauer tree algebras, a class of algebras that contains blocks of group algebras with cyclic defect groups. We show that there is a unique grading up to graded Morita equivalence and rescaling on an arbitrary basic Brauer tree algebra. The third chapter is devoted to the study of gradings on tame blocks of group algebras. We study extensively the class of blocks with dihedral defect groups. We investigate the existence, positivity and tightness of gradings, and we classify all gradings on these blocks up to graded Morita equivalence. The last chapter deals with the problem of transferring gradings via stable equivalences between blocks of group algebras. We demonstrate on three examples how such a transfer via stable equivalences is achieved between Brauer correspondents, where the group in question is a TI group.

Resumo: Em [6] são apresentadas condições necessárias e suficientes para a estabilidade estrutural e o teorema de densidade para campos de vetores em 2-variedades com singularidades simples dos seguintes tipos: cone, guarda-chuva de Whitney, ponto duplo e ponto triplo. Nesta tese, estudamos os fluxos induzidos por estes campos de vetores, que denominamos fluxos Gutierrez-Sotomayor, do ponto de vista topológico utilizando a teoria de Conley. Apresentamos uma fórmula dinâmico-topológica que relaciona o índice de Conley de uma variedade com singularidades simples M que possui uma estratificação que a decompõe numa união disjunta da sua parte regular e da sua parte singular. Usando essa estratificação mostramos que se a singularidade está na parte singular S de M o seu índice pode ser calculado tanto com respeito a M como com respeito a S. Definimos uma função de Lyapunov, neste contexto, e mostramos sua existência para fluxos sem órbitas periódicas e sem ciclos singulares. Em seguida, por uma análise da seqüência de homologia longa exata de um par índice determinamos propriedades que um grafo de Lyapunov deve satisfazer para estar associado a um fluxo. Também abordamos a questão da realização de grafos de Lyapunov abstratos. Para isto, primeiramente apresentamos a igualdade de Poincaré-Hopf, para o caso bidimensional, que caracteriza a relação entre o primeiro número de Betti das 1-variedades ramificadas que são fronteiras de um bloco isolante com seu número de componentes de fronteira e o índice numérico de Conley. Em seguida, mostramos que dados números inteiros positivos que satisfaçam a condição de Poincaré-Hopf sempre é possível construir um bloco isolante que satisfaz estes dados dinâmicos e homológicos
Abstract: In [6] a characterization and genericity theorem for C1-structurally stable vector fields tangent to a 2-dimensional compact subset M of Rk are established. Also in [6], new types of structurally stable singularities and periodic orbits are presented. In this thesis we study the continuous flows associated to these vector fields, which we refer to as the Gutierrez-Sotomayor flows on manifolds M with simple singularities using Conley Index Theory. We consider a stratification of M which decomposes it into a union of its regular and singular strata. We prove certain Euler type formulas which relate topology of M and dynamics on the singular strata. We show the existence of a Lyapunov function for Gutierrez-Sotomayor flows without periodic orbits and singular cycles in this context. Using long exact sequence analysis of index pairs we determine necessary and sufficient conditions for a Gutierrez-Sotomayor flow to be defined on an isolating block. We organize this combinatorially with the aid of Lyapunov graphs and using a Poincar'e-Hopf equality we give necessary conditions for a Lyapunov graph to be associated to a Gutierrez-Sotomayor flow and we also prove these conditions are sufficient

Full text
Abstract:
This thesis consists of four main chapters, together with a general introduction and conclusion. The thesis examines, both separately and together, the formation of trade blocs and global market integration. All the models use a partial equilibrium framework, with firms competing as Cournot oligopolists. Chapter 2 presents two models of trade bloc formation under segmented markets. In the first model, with common constant marginal costs, global free trade is optimal for all countries when there are no more than four countries, but with five or more countries there is an incentive to form a trade bloc containing most countries, but excluding at least one. The second model introduces a cost function where a firm's marginal cost is lower when it is located in a larger trade bloc, with little effect on the results. Chapter 3 analyses the formation of trade blocs between countries with different market sizes under segmented markets. The formation of a two country customs union or free trade area will always raise the smaller country's welfare, while the larger country will usually lose from a free trade area, and sometimes from a customs union. Chapter 4, which is joint work with David R. Collie and Morten Hviid, presents a model of strategic trade policy under integrated markets, under complete and incomplete information. In the former case, a low cost country will give an export subsidy which is fully countervailed by the high cost country's import tariff. In the simultaneous signalling game, each country's expected welfare is higher than under free trade. Chapter 5 considers models of trade bloc formation under integrated markets. With common constant costs, there is no incentive for blocs to form. When costs are decreasing in membership of a bloc, either global free trade is optimal or countries would prefer to belong to the smaller of two blocs.

Abstract:
Periodic structure is a type of periodic medium. Their main characteristics are defined by their unit cell, which is the cell that by repeating it, the lattice is constructed. The main advantage of such structure is that the wave propagation in it can be investigated by using the application of Floquet-Bloch theorem and therefore investigating only a single unit cell. This feature highly reduces the computational cost. In this work a two-dimensional lattice is built using a tensegrity structural unit cell. A tensegrity structure is consist of tension and compression components arranged in a discontinuous system. The dispersion curve is plotted along the edges of IBZ to understand the effect of pre-tension and pre-compression on the band gaps in two cases of a lattice made of only tension components, i.e. cables or compression components, i.e. bars, and a two-dimensional tensegrity system.

In this paper, we present an application of the Floquet-Bloch theorem in the context of electrodynamics for vibroacoustic power flow optimization by mean of distributed and shunted piezoelectric patches. The main purpose of this work is first to propose a dedicated numerical approach able to compute the multi-modal wave dispersions curves into the whole first Brillouin zone for periodically distributed 2D shunted piezomechanical systems. By using two specific indicators evaluating the evanescent part of Bloch’s waves and the induced electronic damping, we optimize the piezoelectric shunting electrical impedance for controlling energy diffusion into the proposed semi-active distributed set of cells. Sound radiation efficiency is also analyzed for showing the effects of such smart metamaterial for controlling acoustical noise.

Abstract:
Using a generalized form of Bloch’s theorem, we derive the dispersion relation of a viscously damped locally resonant metamaterial modeled as an infinite mass-in-mass lumped parameter chain. For comparison, we obtain the dispersion relation for a statically equivalent Bragg-scattering mass-spring chain that is also viscously damped. For the two chains, we prescribe identical damping levels in the dashpots and compare the damping ratio associated with all propagating Bloch modes. We find that the locally resonant metamaterial exhibits higher dissipation throughout the spectrum which indicates a damping emergence phenomena due to the presence of local resonance. This phenomenon, which we define as metadamping, provides a new paradigm for the design of material systems that display both high damping and high stiffness. We conclude our investigation by quantifying the degree of metadamping as a function of the long-wave speed of sound in the medium or the static stiffness.

Abstract:
This paper introduces a novel way to augment the knowledge and methods of rigidity theory to the topological decomposition and synthesis of gear train systems. A graph of gear trains, widely reported in the literature of machine theory, is treated as a graph representation from rigidity theory—the Body-Bar graph. Once we have this Body-Bar graph, methods and theorems from rigidity theory can be employed for analysis and synthesis. In this paper we employ the pebble-game algorithm, a computational method which allows determination of the topological mobility of mechanisms and the decomposition of gear trains into basic building blocks—Body-Bar Assur Graphs. Once we gain the ability to decompose any gear train into standalone components (Body-Bar Assur Graphs), this paper suggests inverting the process and applying the same method for synthesis. Relying on rigidity theory operations (Body-Bar extension, in this case), it is possible to construct all of the Body-Bar Assur Graphs, meaning the building blocks of gear trains. Once we have these building blocks at hand, it is possible to recombine them in various ways, providing us with a topological synthesis method for constructing gear trains. This paper also introduces a transformation between the Body-Bar graph and other graph representations used in mechanisms, thus leaving room for the application of the proposed synthesis and decomposition method directly to known graph representations already used in machine theory.
