Abstract: In this paper we apply the theory of Markov chains to prove the converse to the mean value theorem for harmonic functions. And in a λ-Hölder space we derive convergent rate of n-fold convolution of averaging operator.

Key words: harmonic function, Markov chains, martingale, λ-Hölder space
