Directed random walk with random restarts: The Sisyphus random walk. [PDF]

open access: yesPhysical Review E, 2016
In this paper we consider a particular version of the random walk with restarts: random reset events which suddenly bring the system to the starting value.

Random walk over a hypersphere

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
In a recent paper the author had shown that a special case of S. M. Joshi transform (so named after the author's reverent father) of distributions (Sba f)(x)=〈f(y),  lFl(a0;b0;ixy)  lFl(a;b;−2ixy)〉 is a characteristic function of a spherical ...

Adjusting the Trapping Process of a Directed Weighted Edge-Iteration Network

open access: yesFrontiers in Physics, 2022
Controlling the trapping process is one of the important themes in the study of random walk in real complex systems. We studied two types of random walks that are different from the traditional random walk on a directed weighted network.

A random walk down Main Street

open access: yesTeMA: Journal of Land Use, Mobility and Environment, 2016
US suburbs have often been characterized by their relatively low walk accessibility compared to more urban environments, and US urban environments have been char- acterized by low walk accessibility compared to cities in other countries.

Strategies and first-absorption times in the random walk game [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2023
Purpose of this work is to determine the average time to reach the boundaries, as well as to identify the strategy in the game between two players, controlling point movements on the finite square lattice using an independent choice of strategies.

Convergence of dependent walks in a random scenery to fBm-local time fractional stable motions [PDF]

open access: yes, 2008
It is classical to approximate the distribution of fractional Brownian motion by a renormalized sum $ S_n $ of dependent Gaussian random variables. In this paper we consider such a walk $ Z_n $ that collects random rewards $ \xi_j $ for $ j \in \mathbb Z,

Symmetric exclusion as a random environment: hydrodynamic limits [PDF]

open access: yes, 2014
We consider a one-dimensional continuous time random walk with transition rates depending on an underlying autonomous simple symmetric exclusion process starting out of equilibrium.

Quantum random walks in optical lattices [PDF]

open access: yes, 2002
We propose an experimental realization of discrete quantum random walks using neutral atoms trapped in optical lattices. The random walk is taking place in position space and experimental implementation with present day technology --even using existing ...

Linearly edge-reinforced random walks

open access: yes, 2006
We review results on linearly edge-reinforced random walks. On finite graphs, the process has the same distribution as a mixture of reversible Markov chains. This has applications in Bayesian statistics and it has been used in studying the random walk on

A multifractal random walk

open access: yes, 2000
We introduce a class of multifractal processes, referred to as Multifractal Random Walks (MRWs). To our knowledge, it is the first multifractal processes with continuous dilation invariance properties and stationary increments.
