一类随机环境中可跳无穷远点的随机游动

A Class of Random Walks with Unbounded Jumps in Random Environments

对一类随机环境中可跳无穷远点的随机游动模型进行了研究,利用马氏键方面的2个引理和推移算子,得出了该模型的一个常返性准则.

We study the model of random walk with possible unbounded jumps in random environments. Using two lemma of Makov theory and shift operator, we obtain a recurrence criterion.
