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 ...

A quenched functional central limit theorem for random walks in random environments under (T)γ [PDF]
, 2016 We prove a quenched central limit theorem for random walks in i.i.d. weakly elliptic random environments in the ballistic regime. Such theorems have been proved recently under the assumption of large finite moments for the regeneration times.

Random walk with barycentric self-interaction [PDF]
, 2010 We study the asymptotic behaviour of a $d$-dimensional self-interacting random walk $X_n$ ($n = 1,2,...$) which is repelled or attracted by the centre of mass $G_n = n^{-1} \sum_{i=1}^n X_i$ of its previous trajectory. The walk's trajectory $(X_1,...,X_n)

New Journal of Physics, 2018 A considerable number of systems have recently been reported in which Brownian yet non-Gaussian dynamics was observed. These are processes characterised by a linear growth in time of the mean squared displacement, yet the probability density function of ...

Branching Processes in Random Environment with Sibling Dependence [PDF]
Journal of Mathematical Sciences, 2020 We consider a population of particles with unit life length. Dying each particle produces offspring whose size depends on the random environment specifying the reproduction law of all particles of the given generation and on the number of relatives of the particle.

Birth and Death Processes in Random Environments [PDF]
, 1993 This thesis treats birth and death processes in random environments. They are modelled by Markov processes in Z+2, where the first component represents the object of interest, the "birth and death process", and the second component represents the random ...

φ-branching processes in a random environment [PDF]
Applicationes Mathematicae, 1984 Let \(\phi\) be a function mapping the set of non-negative integers into itself such that \(\phi (0)=0\). Consider a sequence of integer valued random variables \(\{Z_ n\), \(n=0,1,...\}\) and suppose that they satisfy the condition \[ Z_ 0=m,\quad E(s^{Z_{n+1}}| {\mathcal F}_ n({\bar\xi }))=[f_{\xi_ n}(s)]^{\phi (Z_ n)},\quad n\geq 0,| s|\leq 1 ...
