瞬态随机游动值域的界

Boundary of the Range of Transient Random Walk

Amine Asselah, Bruno Schapira

摘要:

本文研究了$d\ge 3$上的$\mathbb{Z}^d$的简单随机游动在瞬态区域的范围边界。我们表明,体积的范围和它的边界主要不同的鞅。作为结果,我们得到了一个界的方差阶$n\log n$在三维。我们还建立了四维及更高维的中心极限定理。

英文摘要:

We study the boundary of the range of simple random walk on $\mathbb{Z}^d$ in the transient regime $d\ge 3$. We show that volumes of the range and its boundary differ mainly by a martingale. As a consequence, we obtain a bound on the variance of order $n\log n$ in dimension three. We also establish a central limit theorem in dimension four and larger.
