Neste trabalho estudamos generalizações do Método de Melnikov para sistemas descontínuos no plano. Neste sentido, inicialmente abordamos esse problema como uma variação do estudo [1] onde um campo Hamiltoniano que admite um ciclo heteroclínico, cujo interior é folheado de órbitas periódicas, é perturbado por um campo Hamiltoniano não autonomo. Neste trabalho estendemos esse resultado para perturbações mais gerais (não conservativas) e apresentamos funções de Melnikov nesse novo contexto. Finalmente, abordamos o problema mais geral, relativo à perturbação de campos não conservativos, onde a função de Melnikov, associada a órbita heteroclínica, é obtida.
In this work we study generalizations of Melnikov's method to planar discontinuous dynamical system. Initially we study this problem as a variation of the work [1] where a Hamiltonian vector field that admits an heteroclinic cycle with its interior foliated by a family of periodic orbits is perturbed by a Hamiltonian perturbation. In this work we extended the results to more general perturbation (non conservative) and we show the Melnikov's functions in this new context. Finally, we approach a more general problem related to a perturbation of the non-conservative vector field where we obtained the Melnikov's function that is associated with a heteroclínic orbit.

Pełny tekst źródłaThe main subject of this thesis is the study first order Hamilton Jacobi equations posed in certain classes of metric spaces. Furthermore, the Hamiltonian of these equations can potentially present some structured discontinuities.In the first part of this thesis, we study a discontinuous first order Hamilton Jacobi Bellman equation defined on a stratification of R^N. The latter is a finite and disjoint union of smooth submanifolds of R^N called the the subdomains of R^N. On each subdomain, a continuous Hamiltonian is defined on it, However the global Hamiltonian in R^N presents discontinuities once one goes from one subdomain to the other. We give an optimal control interpretation of this problem and we use nonsmooth analysis techniques to prove that the value function is the unique viscosity solution to the discontinuous Hamilton Jacobi Bellman equation in this setting. The uniqueness of the solution is guaranteed by means of a strong comparison principle valid for any lower semicontinuous supersolution and any upper semicontinuous subsolution. As far as existence of the solution is concerned, we use the dynamic programming principle verified by the value function to prove that it is a viscosity solution of the discontinuous Hamilton Jacobi equation. Moreover, we prove some stability results in the presence of perturbations on the discontinuous Hamiltonian. Finally, by virtue of the comparison principle, we prove a general convergence result of monotone numerical schemes approximating this problem.The second part of this thesis is concerned with defining a novel notion of viscosity for first order Hamilton Jacobi equations defined in proper CAT(0) spaces. A metric space is said to be a CAT(0) space if, roughly speaking, it is a geodesic space and its geodesic triangles are "thinner" than the triangles of the Euclidean plane. They can be seen as a generalization of Hilbert spaces or Hadamard manifolds. Typical examples of CAT(0) spaces include Hilbert spaces, metric trees and networks obtained by gluing a finite number of half-spaces along their common boundary. We exploit the additional structure that these spaces enjoy to study stationary and time-dependent first order Hamilton-Jacobi equation in them. In particular, we want to recover the main features of viscosity theory: the comparison principle and Perron's method}.We define the notion of viscosity using test functions that are Lipschitz and can be represented as a difference of two semiconvex function. We show that this new notion of viscosity coincides with the classical one in R^N by studying the examples of Hamilton Jacobi Bellman and Hamilton Jacobi Isaacs' equations. Furthermore, we prove existence and uniqueness of the solution of Eikonal type equations posed in networks that can result from gluing half-spaces of different Hausdorff dimension.In the third part of this thesis, we study a Mayer optimal control problem on the space of Borel probability measures over a compact Riemannian manifold M. This is motivated by certain situations where a central planner of a deterministic controlled system has only imperfect information on the initial state of the system. The lack of information here is very specific. It is described by a Borel probability measure along which the initial state is distributed. We define the new notion of viscosity in this space in a similar manner as in the previous part by taking test functions that are Lipschitz and can be written as a difference of two semiconvex functions. With this choice of test functions, we extend the notion of viscosity to Hamilton Jacobi Bellman equations in Wasserstein spaces and we establish that the value function is the unique viscosity solution of a Hamilton Jacobi Bellman equation in the Wasserstein space over M

Pełny tekst źródłaLe cas des images discontinues n'était compris que partiellement. La première contribution de ce travail est de traiter complètement le cas des images discontinues en considérant comme modèle d'image discontinues l'espace des fonctions à variations bornées. On apporte des outils techniques pour traiter les discontinuités dans le cadre d'appariement par difféomorphismes. Ces résultats sont appliqués à la formulation Hamiltonienne des géodésiques dans le cadre d'un nouveau modèle qui incorpore l'action d'un difféomorphisme sur les niveaux de grille de l'image pour prendre en compte un changement d'intensité. La seconde application permet d'étendre la théorie des métamorphoses développée par A.Trouvé et L.Younes aux fonctions discontinues. Il apparait que la géométrie de ces espaces est plus compliquée que pour des fonctions lisses.
La seconde partie de cette thèse aborde des aspects plus probabilistes du domaine. On étudie une perturbation stochastique du système Hamiltonien pour le cas de particules (ou landmarks). D'un point de vue physique, on peut interpréter cette perturbation comme des forces aléatoires agissant sur les particules. Il est donc naturel de considérer ce modèle comme un premier modèle de croissance de forme ou au moins d'évolutions aléatoires de formes.
On montre que les solutions n'explosent pas en temps fini presque sûrement et on étend ce modèle stochastique en dimension infinie sur un espace de Hilbert bien choisi (en quelque sorte un espace de Besov ou Sobolev sur une base de Haar). En dimension infinie la propriété précédente reste vraie et on obtient un important (aussi d'un point de vue numérique) résultat de convergence du cas des particules vers le cas de dimension infinie. Le cadre ainsi développé est suffisamment général pour être adaptable dans de nombreuses situations de modélisation.
