Vonseel, Audrey. "Hyperbolicité et bouts des graphes de Schreier." Thesis, Strasbourg, 2017. http://www.theses.fr/2017STRAD025/document.
Full textThis thesis is devoted to the study of the topology at infinity of spaces generalizing Schreier graphs. More precisely, we consider the quotient X/H of a geodesic proper hyperbolic metric space X by a quasiconvex-cocompact group H of isometries of X. We show that this quotient is a hyperbolic space. The main result of the thesis indicates that the number of ends of the quotient space X/H is determined by equivalence classes on a sphere of computable radius. In the context of group theory, we show that one can construct explicitly groups and subgroups for which there are no algorithm to determine the number of relative ends. If the subgroup is quasiconvex, we give an algorithm to compute the number of relative ends
Roualland, Olivier. "Développements asymptotiques d'intégrales-fibres sous certaines conditions géométriques." Nice, 2002. http://www.theses.fr/2002NICE5778.
Full textIn this work, we prove the existence of asymptotic expansions for fiber integrals of several holomorphic functions under strong geometric conditions called "Loeser-Sabbah". The main idea is to perform a base change in the target space of the morphism so that the Loeser-Sabbah conditions are satisfied locally. We prove that the multi-variate Mellin complex transform induces a one to one correspondence between the class of functions with a asymptotic expansion in Nilsson monomials, and the class of meromorphic functions that verify certain appropriate conditions. We also justify the existence of Bernstein-Sato functional equations with regular holonomic distributions coefficients. The existence of "good Kashiwara operators" will also be established. We then prove that the family of the Mellin transform of the inverse image of the fiber integrals by a base change belongs to the class of meromorphic functions; thus we get expansions expressed locally as finite sums of Nilsson monomials with indefinitely derivable coefficients

Full textIn this thesis we are considering the vectorial damped wave equation on a compact and smooth Riemannian manifold without boundary. The damping term is a smooth function from the manifold to the space of Hermitian matrices of size n. The solutions of this équation are thus vectorial. We start by computing the best exponential energy decay rate of the solutions in terms of the damping term. This allows us to deduce a sufficient and necessary condition for strong stabilization of the vectorial damped wave equation. We also show the appearance of a new phenomenon of high-frequency overdamping that did not exists in the scalar case. In the second half of the thesis we look at the asymptotic distribution of eigenfrequencies of the vectorial damped wave equation. Were show that, up to a null density subset, all the eigenfrequencies are in a strip parallel to the imaginary axis. The width of this strip is determined by the Lyapunov exponents of a dynamical system defined from the damping term

Full textThis thesis is devoted to study the stabilization of some locally coupled systems. First, we study the stability of a one-dimensional coupled wave equations with two interior non smooth viscous dampings where we establish exponential stability. Second, we study the stabilization of a locally coupled wave equations with only one internal viscoelastic damping of Kelvin-Voigt type. Both the damping and the coupling coefficients are non smooth. Using a spectrum approach, we prove the non-uniform stability of the system. Next, using a frequency domain approach, combined with a piecewise multiplier technique and the construction of a new multiplier satisfying some ordinary differential equations, we show that the energy of the smooth solution of the system decays polynomially. Third, we investigate the energy decay of hyperbolic systems of wave-wave, wave-Euler Bernoulli beam and beam-beam types. Indeed, the two equations are coupled through boundary connection with only one localized non smooth fractional Kelvin Voigt damping. We establish a polynomial energy decay rate. Finally, we study the stability of a multidimensional system of two wave equations coupled by velocities with only one localized non-smooth Kelvin-Voigt damping. By using a spectral analysis, we prove the non uniform stability of the system. Further, using a frequency domain approach combined with a multiplier technique, we establish some polynomial stability results by considering different geometric conditions on the coupling and the damping domains. In addition, in the absence of any geometric condition, we establish two polynomial energy decay rates of the system on a square domain

The first result is based on an algebric method and give an estimation of the eigenvalues in euclidean spaces and homogeneous manifolds. The second result is an estimation of the egenvalues in terms of the Ricci curvature of the manifold

Full textHow learning occurs has been a long-standing question in neuroscience. Since the first demonstration that the strength wiring up neurons can be persistent, the study of neuronal connections, the synapses, became a path to understanding memory formation. In the 70s, the first electrophysiology methods to modify the synaptic strength were discovered, leading to the evidence of how synapses subjected to stimulation are plastic. Such a form of synaptic plasticity was predicted two decades before by a theoretical synaptic rule coined by the neuropsychologist Donald Hebb. The possibility that a devised rule could explain memory motivated the birth of theories providing new questions and mechanistic representations of the brain's functioning. The diversification of techniques allowed researchers to investigate in depth the nature of synaptic rules. However, the heterogeneity of experimental conditions adopted by different laboratories implicated that the same stimulation pattern could produce different synaptic modifications. The observed heterogeneity in the methods and outcomes have hindered the formalization of a coherent view on how synaptic plasticity works. To fill this gap, this thesis developed a stochastic computational model of the rat CA3-CA1 glutamatergic synapse to explain and gain insights into how experimental conditions affect plasticity outcomes. I uncovered a new plasticity rule that accounts for methodological differences such as developmental aspects, extracellular medium and temperature influences on synaptic plasticity outcome. The model relies on an expanded version of the previous methods to predict synaptic plasticity, modified to handle combined dynamics. That is achieved by introducing a geometrical readout to interpret the dynamics of two calcium-binding enzymes controlling the induction of plasticity. In this way, the model covers classical and recent stimulation paradigms (e.g. STDP, FDP) using a single rule parameter set. Finally, the model's robustness is tested for in vivo-like spike time irregularity showing how different protocols converge to the same outcome when regularity is altered. This model allows one to obtain testable predictions since it links the simulated variables to the specificity needed to describe a plasticity protocol. Although the model is specific to a single CA3-CA1 synapse, the study's insights may be generalized to other types, enabling a deeper understanding of the rules of synaptic plasticity and learning
