Texto completoWe study certain discrete quantum dynamical systems which are described by unitary operators U acting on the space of square integrable functions defined on the vertices of a countably infinite graph. For initial conditions x the orbits of the system are defined by the iterations Unx for integer n. We consider classes of operators U which depend on parameters. We are interested in topological spectral properties meaning that they are characterized by integers which depend continuously on the parameters of the system. We answer questions which are based on recent observations and applications in physical and information sciences. We state and prove proper mathematical results which apply to some of these observations. In this the sis we present four results: in one spatial dimension and for a class of quantum walks we proved the existence of eigenvalues which are constant with respect to continuous and compact perturbations. In two dimensions we have obtained results on occurrence of stable absolutely continuous spectrum covering the whole unit circle for three different lattice models. We employed several mathematical tools: We used the theory of fibered operators to exhibit systematically the spectral properties of translation invariant operators U. For our operator topological considerations, we put to use the class of Fredholm operators and in particular the complete characterization of its connected components by the index. For the case of the constant eigenvalues we proved a non-trivial and explicit lower bound on their number using the index theorem for Toeplitz operators. We employed the theory of the relative index of a pair of orthogonal projections for our study of the full absolutely continuous spectrum. For each of the three cases we established its non-triviality for a pair involvingU, and then made use of recently proved results concerning the implications on the spectrum of U

Texto completoThe main issue of the thesis is the study of the asymptotic behaviour of optimal transportation problems. Such problems occurs in economy and signal theory. Each of them consists in finding the best discrete measure u wich minimizes the transport to an absolute continuous measure f, subject to a constraint of the kind H(u)£m where H is a given entropy functional. In a first step, we study the case where f is a uniform density on a cube and H(u)=S (u(x))a with aÎ[0,1[. In the general case, we reduce the question of the asymptotic behaviour to the description of the G-limit of a suitable functionnal naturally associated to the Wasserstein distance. In the second part of the thesis, we present new applications of transport problems with time depending cost. The particular case of homogeneous cost (depending only on the average speed) allows us to write optimality conditions for the Wasserstein transport Wp (p>1) as a system of equations (eikonal-diffusion) written in the sense of measures. This generalizes the results obtained in the case p=1 ( L. Evans and W. Gangbo, G. Bouchitté and G. Buttazzo) and those of Brenier (p>1) to the case where the transported measures are singular

Texto completoThis thesis is decomposed into three parts. The main part is devoted to the study of spin polarized currents in semiconductor materials. An hierarchy of microscopic and macroscopic models are derived and analyzed. These models takes into account the spin relaxation and precession mechanisms acting on the spin dynamics in semiconductors. We have essentially two mechanisms : the spin-orbit coupling and the spin-flip interactions. We begin by presenting a semiclassical analysis (via the Wigner transformation) of the Schrödinger equation with spin-orbit hamiltonian. At kinetic level, the spinor Vlasov (or Boltzmann) equation is an equation of distribution function with 2x2 hermitian positive matrix value. Starting then from the spinor form of the Boltzmann equation with different spin-flip and non spin-flip collision operators and using diffusion asymptotic technics, different continuum models are derived. We derive drift-diffusion, SHE and Energy-Transport models of two-components or spin-vector types with spin rotation and relaxation effects. Two numerical applications are then presented : the simulation of transistor with spin rotational effect and the study of spin accumulation effect in inhomogenous semiconductor interfaces. In the second part, the diffusion limit of the linear Boltzmann equation with a strong magnetic field is performed. The Larmor radius is supposed to be much smaller than the mean free path. The limiting equation is shown to be a diffusion equation in the parallel direction while in the orthogonal direction, the guiding center motion is obtained. The diffusion constant in the parallel direction is obtained through the study of a new collision operator obtained by averages of the original one. Moreover, a correction to the guiding center motion is derived. .

Texto completoThis dissertation is devoted to the mathematical investigation of properties of complex socio-economic systems, where individual behaviors, and their interactions, exert a crucial influence on the overall dynamics of the whole system. In order to understand the importance of such an investigation, it is necessary to briefly analyze some conceptual aspects relating to the interaction between applied mathematics and socio-economic sciences. The main issue in this field consists in coupling the usual qualitative interpretation of socio-economic phenomena with an innovative quantitative description by means of mathematical equations. This dialogue, however difficult, is necessary to reach a deeper understanding of socio-economic phenomena, where deterministic rules may be stochastically perturbed by individual behaviors. The difficulty mostly stems from the fact that the behavior of socio-economic systems, where the collective dynamics differ from the sum of the individual behaviors, is aparadigmatic example of a complex system. The mathematical framework presented in this dissertation is built by suitable developments of the so-called mathematical kinetic theory for active particles, which proved to be a useful reference for applications in many fields of life sciences. The description of a system by the methods of the mathematical kinetic theory essentially implies the definition of the microscopic state space of the in¬teracting entities and of the distribution function over this state space
