As corollaries, we generalize results of Yang and Ye and obtain some limit theorems for frequencies of states, ordered couples of states, and the conditional expectation of a bivariate function on Cayley tree.}, number={10}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Kangkang, Wang}, year={2011}, month={Oct.}, pages={1336-1351} }
