随机游动自相交的渐近方差

An asymptotic variance of the self-intersections of random walks

George Deligiannidis, Sergey Utev

摘要:

我们提出了一个Darboux-Wiener型引理,并应用它获得了一维和二维随机游动自相交方差的精确渐近性。作为推论,我们得到了Kesten和Spitzer在1979年提出的关于随机场景中随机游动的一个中心极限定理.

英文摘要:

We present a Darboux-Wiener type lemma and apply it to obtain an exact asymptotic for the variance of the self-intersection of one and two-dimensional random walks. As a corollary, we obtain a central limit theorem for random walk in random scenery conjectured by Kesten and Spitzer in 1979.
