Random walks in a sparse random environment
We introduce random walks in a sparse random environment on $\mathbb Z$ and investigate basic asymptotic properties of this model, such as recurrence-transience, asymptotic speed, and limit theorems in both the transient and recurrent regimes. The new model combines features of several existing models of random motion in random media and admits a ...

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 environment with Markov dependence on time
We consider a simple model of discrete-time random walk on Ζν, ν=1,2,... in a random environment independent in space and with Markov evolution in time. We focus on the application of methods based on the properties of the transfer matrix and on spectral

Branching random walk in random environment on trees
The authors consider a supercritical branching random walk on a rooted tree with random environment, the special attention being paid to the case where both the branching and the step transition parameters are random quantities. For this model criteria of recurrence (strong recurrence) and transience (strong transience) are presented.

Random walks in random hypergeometric environment [PDF]
We consider one-dependent random walks on Zd in random hypergeometric environment for d≥3. These are memory-one walks in a large class of environments parameterized by positive weights on directed edges and on pairs of directed edges which includes the ...

Random Walks in Random Environment [PDF]
Random walks in random environments (RWRE's) have been a source of surprising phenomena and challenging problems since they began to be studied in the 70's. Hitting times and, more recently, certain regeneration structures, have played a major role in our understanding of RWRE's. We review these and provide some hints on current research directions and

A Two-Stage Mutation Stochastic Model of Carcinogenesis Driven by a Two Level Random Environment [PDF]
In this paper, we present a two-stage stochastic model of carcinogenesis in a two level random environment. The random environment switches between two levels, say, 1 and 2 alternately.

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 ...
