Random walk on random walks: low densities [PDF]

open access: yes, 2017
We consider a random walker in a dynamic random environment given by a system of independent simple symmetric random walks. We obtain ballisticity results under two types of perturbations: low particle density, and strong local drift on particles ...

Doob's Type Inequality and Strong Law of Large Numbers for Demimartingales

open access: yesJournal of Inequalities and Applications, 2010
We establish some maximal inequalities for demimartingales which generalize the result of Wang (2004). The maximal inequality for demimartingales is used as a key inequality to establish other results including Doob's type maximal inequality, strong ...

Weak and strong law of large numbers for weakly negatively dependent random variables under sublinear expectations

open access: yesAIMS Mathematics
In the framework of sublinear expectations, we prove the Marcinkiewicz-Zygmund type weak law of large numbers for an array of row-wise weakly negatively dependent (WND) random variables.

Some strong limit theorems for nonhomogeneous Markov chains indexed by controlled trees

open access: yesJournal of Inequalities and Applications, 2016
In this paper, a kind of infinite, local finite tree T, named a controlled tree, is introduced. Some strong limit properties, such as the strong law of large numbers and the asymptotic equipartition property, for nonhomogeneous Markov chains indexed by T,

Exponential inequalities and a strong law of large numbers for END random variables under sub-linear expectations

open access: yesAIMS Mathematics, 2023
The focus of our work is to investigate exponential inequalities for extended negatively dependent (END) random variables in sub-linear expectations. Through these exponential inequalities, we were able to establish the strong law of large numbers with ...

Some almost sure results for unbounded functions of intermittent maps and their associated Markov chains [PDF]

open access: yes, 2009
We consider a large class of piecewise expanding maps T of [0,1] with a neutral fixed point, and their associated Markov chain Y_i whose transition kernel is the Perron-Frobenius operator of T with respect to the absolutely continuous invariant ...

Moment conditions in strong laws of large numbers for multiple sums and random measures

open access: yes, 2017
The validity of the strong law of large numbers for multiple sums $S_n$ of independent identically distributed random variables $Z_k$, $k\leq n$, with $r$-dimensional indices is equivalent to the integrability of $|Z|(\log^+|Z|)^{r-1}$, where $Z$ is the ...

Complete convergence of randomly weighted END sequences and its application

open access: yesJournal of Inequalities and Applications, 2017
We investigate the complete convergence of partial sums of randomly weighted extended negatively dependent (END) random variables. Some results of complete moment convergence, complete convergence and the strong law of large numbers for this dependent ...
