Entropic repulsion on a rarefied wall [PDF]
We consider the motion of a discrete d-dimensional random surface interacting by exclusion with a rarefied wall. The dynamics is given by the serial harness process.

Random walk in random environment: A counterexample? [PDF]
(The authors describe a family of random walks in random environment which have exponentially decaying correlations and nearest neighbour transition probabilities bounded away from zero, and yet are subdiffusive in any finite dimension. This contradicts the widespread notion that in case of short range correlations, two is the upper critical dimension ...

Moment asymptotics for multitype branching random walks in random environment [PDF]
We study a discrete time multitype branching random walk on a finite space with finite set of types. Particles follow a Markov chain on the spatial space whereas offspring distributions are given by a random field that is fixed throughout the evolution ...

Degenerate random environments [PDF]
AbstractWe consider connectivity properties of certain i.i.d. random environments on, where at each location some steps may not be available. Site percolation and oriented percolation are examples of such environments. In these models, one of the quantities most often studied is the (random) set of vertices that can be reached from the origin by ...

The problem of optimal control in a random environment (also known as the two- armed bandit problem) is considered. The equations for calculating Bayes risks and losses are obtained for incomes with different variances.

Perfect matchings in inhomogeneous random bipartite graphs in random environment
In this note we study inhomogeneous random bipartite graphs in random environment. These graphs can be thought of as an extension of the classical Erd\H os-R\'enyi random bipartite graphs in a random environment.

Random Walks in Random Environments [PDF]
Random walks provide a simple conventional model to describe various transport processes, for example propagation of heat or diffusion of matter through a medium. However, in many practical cases the medium is highly irregular due to defects, impurities, fluctuations etc., and it is natural to model this as random environment.
