Abstract

Abstract : A Markov chain with state space{ 0, …, N } and transition probabilities depending on the current state is studied. The chain can be considered as a discrete Ornstein-Uhlenbeck process. The probability that the process hitsN before 0 is computed explicitly. Similarly, the probability that the process hitsN before− M is computed in the case when the state space is{ − M, …, 0, …, N } and the transition probabilitiesp i, i + 1 are not necessarily the same wheni is positive andi is negative.
