Survival time of random walk in random environment among soft obstacles
(UNIV WASHINGTON, DEPT MATHEMATICS, 2009)
We consider a Random Walk in Random Environment (RWRE) moving in an i.i.d. random field of obstacles. When the particle hits an obstacle, it disappears with a positive probability. We obtain quenched and annealed bounds ...

Sensitivity of the frog model to initial conditions
(Univ Washington, 2019-11)
The frog model is an interacting particle system on a graph. Active particles perform independent simple random walks, while sleeping particles remain inert until visited by an active particle. Some number of sleeping ...

Dynamical properties of random walks
(World Scientific Publ Co Pte Ltd, 2019-06-01)
In this paper, we study dynamical properties such as hypercyclicity, supercyclicity, frequent hypercyclicity and chaoticity for transition operators associated to countable irreducible Markov chains. As particular cases, ...
Reaction rate in an evanescent random walkers system
(2015)
Diffusion mediated reaction models are particularly ubiquitous in the description of phys-ical, chemical or biological processes. The random walk schema is a useful tool for formu-lating these models. Recently, evanescent ...
