Random Walks in Degenerate Random Environments [PDF]
Canadian Journal of Mathematics, 2014 AbstractWe study the asymptotic behaviour of random walks in i.i.d. random environments on . The environments need not be elliptic, so some steps may not be available to the random walker. We prove a monotonicity result for the velocity (when it exists) for any 2-valued environment, and show that this does not hold for 3-valued environments without ...

On comparing configuration graphs robustness in a random environment
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018 We consider configuration graphs with vertex degrees distributed independently according to the power law, with a truncated parameter τ normally distributed on the interval (a, b).

Branching Random Walks in Random Environment
, 2021 We consider branching particle processes on discrete structures like the hypercube in a random fitness landscape (i.e. random branching/killing rates). The main question is about the location where the main part of the population sits at a late time, if ...

Entropic repulsion on a rarefied wall [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 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.

Moment asymptotics for branching random walks in random environment [PDF]
, 2012 We consider the long-time behaviour of a branching random walk in random environment on the lattice ℤd. The migration of particles proceeds according to simple random walk in continuous time, while the medium is given as a random potential of spatially ...

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015 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.

Random Walks in Cooling Random Environments [PDF]
, 2019 We propose a model of a one-dimensional random walk in dynamic random environment that interpolates between two classical settings: (I) the random environment is sampled at time zero only; (II) the random environment is resampled at every unit of time. In our model the random environment is resampled along an increasing sequence of deterministic times.

Random Walks in Random Environments [PDF]
, 2006 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.

Trees with product-form random weights [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 We consider growing random recursive trees in random environment, in which at each step a new vertex is attached according to a probability distribution that assigns the tree vertices masses proportional to their random weights.The main aim of the paper ...
