Abstract

Let X0,X1, . . . be a simple ergodic finite Markov chain.We prove limit theorems for the distribution of the number ξ̄(s, n) of events

{Xi−1 ≠ Xj−1, Xi+k = Xj+k, k = 0, . . . , s − 1}, 1 ≤ i < j ≤ n,

when s, n → ∞. Limit theorems for distributions of some random variables connected with ξ̄(s, n) are derived as corollaries.
