边加强随机游动的渐近性

Asymptotic behavior of edge-reinforced random walks

Franz Merkl, Silke W. W. Rolles

摘要:

本文研究了一般多层梯子上的线性边强化随机游动,其中初始边权值较大。对于无限阶梯,我们表明,该过程可以表示为一个随机环境中的随机游动,给定的随机权重的边缘。边权重在空间中呈指数衰减。该过程收敛于一个平稳过程。我们提供了渐近界的范围内的随机步行者到一个给定的时间,表明它本地化比普通的随机步行者。随机环境中描述的无限体积吉布斯措施。

英文摘要:

In this article, we study linearly edge-reinforced random walk on general multi-level ladders for large initial edge weights. For infinite ladders, we show that the process can be represented as a random walk in a random environment, given by random weights on the edges. The edge weights decay exponentially in space. The process converges to a stationary process. We provide asymptotic bounds for the range of the random walker up to a given time, showing that it localizes much more than an ordinary random walker. The random environment is described in terms of an infinite-volume Gibbs measure.
