Texte intégralO processo de Fleming-Viot é um processo de Markov cujo espaço de estado é um conjunto de medidas de propabilidade. As funções-amostras do processo representam as prováveis possibilidades de transformação das freqüencias de tipos genéticos presentes numa população ao longo do tempo. Obtido como solução de um problema de martingala bem posto para um operador linear construído de forma a modelar diversas características importantes no estudo da genética populacional, como mutação, seleção, deriva genética, entre outras, o processo de Fleming-Viot permite, por meio de uma abordagem matemática unificadora, tratar problemas de complexidade variada. No presente trabalho, estudamos s processs de Fleming-Viot com saltos, introduzidos por Hiraba. Interpretamos biologicamente esse saltos como mudanças abruptas que podem ocorrer, num curto espaço de tempo, durante a evolução de uma população de indivíduos, causadas por epidemias, desastres naturais ou outras catástrofes, e que levam a descontinuidades nas frequências dos tipos gênicos. Apresentamos uma forma de incluir um fator de seleção no processo com saltos, através da aplicação de uma transformação de medida do tipo Girsanov. Em seguida, fazemos uma análise do comportamento assintótico do processo utilizando técnicas de dualidade e acoplamento.

Texte intégralAdaptive dynamics theory is a branch of evolutionary biology which studies the links between ecology and evolution. The biological assumptions that define its framework are those of rare and small mutations and large asexual populations. Adaptive dynamics models describe the population at the level of individuals, which are characterised by their phenotypes, and aim to study the influence of heredity, mutation and selection mechanisms on the long term evolution of the population. The success of this theory comes in particular from its ability to provide a description of the long term evolution of the dominant phenotype in the population as a solution to the “Canonical Equation of Adaptive Dynamics” driven by a fitness gradient, where fitness describes the possibility of mutant invasions, and is constructed from ecological parameters. Two main mathematical approaches to the canonical equation have been developed so far: an approach based on PDEs and a stochastic approach. Despite its success, the stochastic approach is criticised by biologists as it is based on a non-realistic assumption of too rare mutations. The goal of this thesis is to correct this biological controversy by proposing more realistic probabilistic models. More precisely, the aim is to investigate mathematically, under a double asymptotic of large population and small mutations, the consequences of a new biological assumption of frequent mutations on the canonical equation. The goal is to determine, from a stochastic individual-based model, the long term behaviour of the mean phenotypic trait of the population. The question we ask is reformulated into a slow-fast asymptotic analysis acting on two eco-evolutionary time scales. A slow scale corresponding to the dynamics of the mean trait, and a fast scale corresponding to the evolutionary dynamics of the centred and dilated distribution of traits. This slow-fast asymptotic analysis is based on averaging techniques. This method requires the identification and characterisation of the asymptotic behaviour of the fast component and that the latter has ergodicity properties. More precisely, the long time behaviour of the fast component is non-classical and corresponds to that of an original measure-valued diffusion which is interpreted as a centered Fleming-Viot process that is characterised as the unique solution of a certain martingale problem. Part of these results is based on a duality relation on this non-classical process and requires moment conditions on the initial data. Using coupling techniques and the correspondence between Moran's particle processes and Kingman's genealogies, we establish that the centered Fleming-Viot process satisfies an ergodicity property with exponential convergence result in total variation. The implementation of averaging methods, inspired by Kurtz, is based on compactness-uniqueness arguments. The idea is to prove the compactness of the laws of the couple made up of the slow component and the occupation measure of the fast component and then to establish a martingale problem for all accumulation points of the family of laws of this couple. The last step is to identify these accumulation points. This method requires in particular the introduction of stopping times to control the moments of the fast component and to prove that they tend to infinity using large deviation arguments, to reduce the problem initially posed on the real line to the torus case in order to prove compactness, to identify the limit of the fast component by adapting an argument based on Dawson duality, to identify the limit of the slow component and then to move from the torus to the real line
