摘要: 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. 參考: Fred Solomon (1975) Random Walks in a Random Environment, Ann.
