CONVERGENCE THEOREMS FOR A PAIR OF ASYMPTOTICALLY AND MULTIVALUED NONEXPANSIVE MAPPING IN CAT(0) SPACES
Naknimit Akkasriworn, Kritsana Sokhuma · Communications of the Korean Mathematical Society · 2015
In this paper, we prove ${\Delta}$ -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 [13].
