Random Walks in Random Environment (2)
許順吉教授國立中央大學數學系 上午 10:00–12:00 鴻經館 107 室This is a continuation of our previous discussion on Solomon’s paper.
We will continue to discuss the average speed of a 1-d random walk in random environment.
We explore the stationarity of the sequence of ladder random variables.
Based on this observation, then the ergodic theorem can be applied to derive the average speed of the random walk.
The paper by Kesten-Kozlov-Spitzer is on the CLT of the random walk. We will briefly discuss the paper if the time allows.
