Random walk in random environment: A counterexample? [PDF]
Communications in Mathematical Physics, 1988 (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 ...

Logarithmic speeds for one-dimensional perturbed random walk in random environment [PDF]
, 2007 We study the random walk in random environment on Z+ = f0; 1; 2; : : :g, where the environment is subject to a vanishing (random) perturbation. The two particular cases that we consider are: (i) random walk in random environment perturbed from Sinai's ...

Journal of Building Materials and Structures, 2018 The grains can be of very diverse nature (size, shape, mineralogy, etc), indeed even if each grain is a fairly simple object, the set of grains is a very complex system in which the geometrical and physical properties of the grains, their forces and ...

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).

Random Graphs' Robustness in Random Environment
Austrian Journal of Statistics, 2017 We consider configuration graphs the vertex degrees of which are independent and follow the power-law distribution. Random graphs dynamics takes place in a random environment with the parameter of vertex degree distribution following uniform ...

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 ...

Scaling limit of critical random trees in random environment [PDF]
, 2023 We consider Bienaym\'e-Galton-Watson trees in random environment, where each generation $k$ is attributed a random offspring distribution $\mu_k$, and $(\mu_k)_{k\geq 0}$ is a sequence of independent and identically distributed random probability ...
