Published in 2017 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-017-2996-5

Abstract: In this paper, we study random walks $${g_n=f_{n-1}\ldots f_0}$$gn=fn-1…f0 on the group Homeo (S1) of the homeomorphisms of the circle, where the homeomorphisms fk are chosen randomly, independently, with respect to a same probability measure… read more here.

Published in 2019 at "Journal of Nonlinear Science"

DOI: 10.1007/s00332-018-9521-7

Abstract: In this paper, we study the dynamics of nonlinear random walks. While typical random walks on networks consist of standard Markov chains whose static transition probabilities dictate the flow of random walkers through the network,… read more here.

Published in 2021 at "Statistical Papers"

DOI: 10.1007/s00362-021-01237-0

Abstract: Consider two independent random walks. By chance, there will be spells of association between them where the two processes move in the same direction, or in opposite direction. We compute the probabilities of the length… read more here.

Published in 2021 at "Probability Theory and Related Fields"

DOI: 10.1007/s00440-021-01067-z

Abstract: We study the isoperimetric and spectral profiles of certain families of finitely generated groups defined via actions on labelled Schreier graphs and simple gluing of such. In one of our simplest constructions—the pocket-extension of a… read more here.

Published in 2017 at "Journal of Statistical Physics"

DOI: 10.1007/s10955-017-1876-x

Abstract: In this work we consider open quantum random walks on the non-negative integers. By considering orthogonal matrix polynomials we are able to describe transition probability expressions for classes of walks via a matrix version of… read more here.

Published in 2019 at "Journal of Statistical Physics"

DOI: 10.1007/s10955-020-02547-7

Abstract: Network epidemics is a ubiquitous model that can represent different phenomena and finds applications in various domains. Among its various characteristics, a fundamental question concerns the time when an epidemic stops propagating. We investigate this… read more here.

Published in 2017 at "Journal of Mathematical Sciences"

DOI: 10.1007/s10958-017-3405-5

Abstract: We consider random multi-dimensional lattice walks bounded by a hyperplane, calling them walks over multi-dimensional simplicial lattices. We demonstrate that generating functions of these walks are dynamical correlation functions of a certain type of exactly… read more here.

DOI: 10.1007/s10958-020-05074-8

Abstract: A branching random walk on two-dimensional lattices corresponding to graphene and stanene is considered. It is assumed that sources of branching are located on lattices periodically. An asymptotics of the mean value of particles in… read more here.

Published in 2021 at "Annals of Physics"

DOI: 10.1016/j.aop.2021.168613

Abstract: Abstract It has recently been proved that, in the presence of a static absorbing trap, Sisyphus random walkers with a restart mechanism are characterized by exponentially decreasing asymptotic survival probability functions. Interestingly, in the present… read more here.
