Biased Random Walk on $Z_{+}$ with Traps of Linearly Increasing Depth

Hua-Ming Wang, Ning Wang

We study a $λ$ -biased random walk $(X_{n})_{n \geq 0}$ on the deterministic infinite rooted tree $T = {(i, j) : i \geq 0, 0 \leq j \leq i}$ , whose backbone is ${(i, 0) : i \geq 0}$ and, f…

Beyond Poisson Approximation: Sums of Markovian Bernoulli Variables with Applications to Brownian Motions and Branching Processes

Hua-Ming Wang, Shuxiong Zhang

Let ${η_{i}}_{i \geq 1}$ be a sequence of dependent Bernoulli random variables. While the Poisson approximation for the distribution of $\sum_{i = 1}^{n} η_{i}$ has been extensively studied…

Times of a branching process with immigration in varying environment attaining a fixed level

Hua-Ming Wang

Consider a branching process ${Z_{n}}_{n \geq 0}$ with immigration in varying environment. For $a \in {0, 1, 2, ...},$ let $C = {n \geq 0 : Z_{n} = a}$ be the collection of times at which the po…

Local time, upcrossing time and weak cutpoints of a spatially inhomogeneous random walk on the line

Hua-Ming Wang

In this paper, we study a transient spatially inhomogeneous random walk with asymptotically zero drifts on the lattice of the positive half line. We give criteria for the finitenes…

Cutpoints of (1,2) and (2,1) random walks on the lattice of positive half line

Hua-Ming Wang, Lanlan Tang

In this paper, we study (1,2) and (2,1) random walks in varying environments on the lattice of positive half line. We assume that the transition probabilities at site $n$ are asymp…

Regeneration of branching processes with immigration in varying environments

Baozhi Li, Hongyan Sun, Hua-Ming Wang

In this paper, we consider certain linear-fractional branching processes with immigration in varying environments. For $n \geq 0,$ let $Z_{n}$ counts the number of individuals of the $n…
