Brick walls and trees with catastrophes
Ariane Carrance (Université de Vienne)
In this talk, I will present a new model of random trees that generalizes Bienaymé-Galton-Watson (BGW) trees, by allowing spatial correlations between the deaths of [...]

Probabilistic sigma models
Antti Kupiainen (Université d'Helsinski)
In a probabilistic formulation of quantum field theory a sigma model is a theory of a random field defined on space (a manifold in general) [...]

Spectral distribution of tensor products of random matrices.
Patrick OLIVEIRA SANTOS (New York University Abu Dhabi)
In this talk, I will discuss the spectral distribution of tensor products of random matrices. While random matrices can often be viewed as noncommutative operators, [...]

Invasion Dynamics of a Birth–Death Process in a Quasi-Critical Regime: Applications to Cancer.
Nadia BELMABROUK (École Polytechnique)
During the emergence of cancer, a mutant cell can develop its own subpopulation and progressively invade the resident population. We start from a single mutant [...]

Separation cut-off phenomenon for Brownian motions in high dimensional harmonic manifolds
Magalie BÉNÉFICE (IECL, Nancy)
The cut-off phenomenon for Markov processes is about the abrupt transition to equilibrium. During this talk, I aim to explain how this phenomenon can be [...]

Directed polymer in correlated environment
Francesca Cottini (Sorbonne Université)
Directed polymers in random environments describe a perturbation of the simple random walk given by a random disorder (environment). The partition functions of this model [...]

Convergence of non-reversible Markov processes via lifting and flow Poincaré inequality
Léo HAHN (Université de Neuchâtel)
We propose a general approach for quantitative convergence analysis of non-reversible Markov processes, based on the concept of second-order lifts and a variational approach to [...]
