The Spectral Method and the Central Limit Theorem for General Markov Chains*

Resumo

Markov chains with an arbitrary phase space are considered, which, in general, do not satisfy the uniform ergodicity condition. A modification of the spectral method is devised that allows one to obtain limit theorems for such chains. The proof of the central limit theorem is given, the Athreya– Ney–Nummelin condition not being satisfied.
