Diffusivity of a random walk on random walks [PDF]
Random Structures & Algorithms, 2014 We consider a random walk $(Z^{(1)}_n, ..., Z^{(K+1)}_n) \in \mathbb{Z}^{K+1}$ with the constraint that each coordinate of the walk is at distance one from the following one. In this paper, we show that this random walk is slowed down by a variance factor $σ_K^2 = \frac{2}{K+2}$ with respect to the case of the classical simple random walk without ...

Moments of exit times from wedges for non-homogeneous random walks with asymptotically zero drifts [PDF]
, 2013 We study quantitative asymptotics of planar random walks that are spatially non-homogeneous but whose mean drifts have some regularity. Specifically, we study the first exit time $\tau_\alpha$ from a wedge with apex at the origin and interior half-angle $

Non Unitary Random Walks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 Motivated by the recent refutation of information loss paradox in black hole by Hawking, we investigate the new concept of {\it non unitary random walks}.

Random walks in random sceneries and related models* [PDF]
ESAIM: Proceedings and Surveys, 2020 We present random walks in random sceneries as well as three related models: U-statistics indexed by random walks, a model of stratified media with inhomogeneous layers (random one-way streets) and the one-dimensional Lévy-Lorentz gas (random roundabouts

Non Uniform Random Walks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Given $\epsilon _i ∈ [0,1)$ for each $1 < i < n$, a particle performs the following random walk on $\{1,2,...,n\:\}$par If the particle is at $n$, it chooses a point uniformly at random (u.a.r.) from $\{1,...,n-1\}$.

Random walks with sticky barriers
Modern Stochastics: Theory and Applications, 2022 A new class of multidimensional locally perturbed random walks called random walks with sticky barriers is introduced and analyzed. The laws of large numbers and functional limit theorems are proved for hitting times of successive barriers.

Current Trends in Random Walks on Random Lattices
Mathematics, 2021 In a classical random walk model, a walker moves through a deterministic d-dimensional integer lattice in one step at a time, without drifting in any direction.

Osculating Random Walks on Cylinders [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 We consider random paths on a square lattice which take a left or a right turn at every vertex. The possible turns are taken with equal probability, except at a vertex which has been visited before.
