Branching processes and interacting random walks are current topics of research that play an important role in probability theory, with many applications, for example in physics or biology. Interactions between these two themes exist, and one of the aims of the conference is to develop them further. Our goal is to review the recent progress in these very active areas of research, but also to encourage exchanges between different communities; in particular putting forth innovative ideas that could be used more broadly. The aim of the conference is to bring together researchers (PhD students, post-docs, junior and senior researchers) working on a variety of topics revolving around interacting random walks and branching processes, with the idea of fostering discussions and initiating possible collaborations. The conference’s themes are a central part of our ANR Local project.
Les processus de branchement et les marches aléatoires en interactions sont des sujets de recherche actuels qui jouent un rôle important en probabilité et possèdent de nombreuses applications, par exemple en physique ou en biologie. Des interactions existent entre ces deux thèmes, et l’un des but de la conférence est de les développer davantage. L’objectif est de dresser un état des lieux des progrès récents liés à ces domaines de recherche très actifs, mais aussi d’encourager les échanges entre plusieurs communautés ; afin notamment de mettre en avant les idées novatrices qui pourraient être utiles de manière plus large. Le but de la conférence est de rassembler des chercheurs (doctorant·e·s, postdoctorant·e·s, junior·e·s ou confirmé·e·s) travaillant sur des sujets variés tournant autour des marches aléatoires en interactions et des processus de branchement, avec l’envie de favoriser les discussions et d’initier de possibles collaborations. Les thèmes de la conférence forment une partie centrale de notre projet ANR Local.
