This paper studies the distribution function of the time of extinction of a subcritical epidemic, when a large enough proportion of the population has been immunized and/or the infectivity of the infectious individuals has been reduced, so that the e

We code Galton-Walton trees by a continuous height process, in order to give a precise meaning to the convergence of forests of trees. This allows us to establish the convergence of the forest of genealogical trees of the branching process of a large

Dans cette thèse, on étudie la convergence du processus d'exploration de l'arbre généalogique d'un processus de branchement en temps continu non binaire, dans la limite d'une grande population. Dans la première partie, nous donnons une descripti

In this work, we first show that the properly rescaled height process of the genealogical tree of a continuous time branching process converges to the height process of the genealogy of a (possibly discontinuous) continuous state branching process. W

In this work, we study asymptotics of the genealogy of Galton-Watson processes. Thus we consider a offspring distribution such that the rescaled Galton-Watson processes converges to a continuous state branching process (CSBP) with jumps. After we sho

We study the exploration (or height) process of a continuous time non-binary Galton-Watson random tree, in the subcritical, critical and supercritical cases. Thus we consider the branching process in continuous time (Z_{t})_{t\geq 0}, which describes

Biofilms can be considered as more or less complex, highly structured microbial communities attached to a surface. In bacteria, biofilms are formed from clusters of cells of one or more species, producing their own exopolymeric, protective and adhesi
