【Abstract】 In this paper, we study the recurrence of RWIRE on the right half line. In idepedent environment, we provide a sufficient condiction that RWIRE is positive recurrent or is not recurrent by a large law of large numeber. Furthermore, this conclusion is generalized to some special cases. In random environment, we provide sufficient condictions for recurrentce and zero recurrence by boundedness of suquence of numeber.更多还原
