本文主要讨论了在独立但不同分布环境下,半直线上可逗留随机环境中随机游动的常返性和非常返性,并进一步研究了常返性中的正常返性和零常返性.
In this paper, the authors describe and analyze the recurrence of random walks with resting states on half-line in independent and differently distributed random environment. Furthermore, the oppsitive recurrence and null recurrence are studied.
