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 [...]

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 [...]

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 [...]

Extreme paths in oriented 2D Percolation - Enrique Andjel
Enrique Andjel (I2M, Aix-Marseille Université)
A useful result about leftmost and rightmost paths in two dimensional bond percolation is proved. Among the consequences are a natural monotonicity in the probability [...]
Quenched invariance principle for random walks with time-dependent ergodic degenerate weights - Alberto Chiarini
Alberto Chiarini (I2M, Aix-Marseille Université)
We study a symmetric diffusion in divergence form in a stationary and ergodic environment, with measurable unbounded and degenerate coefficients. We prove a quenched invariance [...]
Complémentabilité et maximalité, en théorie ergodique et en théorie des filtrations - Christophe Leuridan
Christophe Leuridan (Institut Fourier, Université de Grenoble-Alpes)
Soit $(E,{\cal E},\pi,T)$ un système dynamique. Un facteur de $T$ est une sous-tribu de ${\cal E}$ invariante par $T$. Un facteur ${\cal A}$ est dit [...]
