Convergence theorems for a pair of asymptotically and multivalued nonexpansive mapping in CAT(0) spaces

摘要

In this paper, we prove $riangle$-convergence theorems for Ishikawa iteration of asymptotically and multivalued nonexpansive mapping in CAT(0) spaces. This results we obtain are analogs of Banach spaces results of Sokhuma cite{So}.
