Equilibrium fluctuations for exclusion processes with conductances in random environments
, 2010 Fix a function W:Rd→R such that W(x1,…,xd)=∑k=1dWk(xk), where d≥1, and each function Wk:R→R is strictly increasing, right continuous with left limits.

Branching processes with deteriorating random environments
Journal of Applied Probability, 2002 We introduce Galton-Watson style branching processes in random environments which are deteriorating rather than stationary or independent. Some primary results on process growth and extinction probability are shown.

Analysis of random walks in dynamic random environments via L^2-perturbations [PDF]
Stochastic Processes and their Applications, 2018 International audienceWe consider random walks in dynamic random environments given by Markovian dynamics on Z^d. We assume that the environment has a stationary distribution \mu and satisfies the Poincaré inequality w.r.t. \mu.

Zero-Range Process in Random Environment [PDF]
, 2021 We survey our recent articles dealing with one dimensional attractive zero range processes moving under site disorder. We suppose that the underlying random walks are biased to the right and so hyperbolic scaling is expected. Under the conditions of our model the process admits a maximal invariant measure.

Strong Dispersal Limitation of Microbial Communities at Shackleton Glacier, Antarctica
mSystems, 2023 Microbial communities can be structured by both deterministic and stochastic processes, but the relative importance of these processes remains unknown. The ambiguity partly arises from an inability to disentangle soil microbial processes from confounding

Fractal Dimensions of Random Trees [PDF]
The Egyptian Statistical Journal, 1994 Our goal in this paper is to determine whether the fractal dimensions (FD) of random trees is finite. Two types of random trees are considered. We first consider spherically symmetric random trees in which all vertices at level n have degree 3 with ...
