Generalized Nonexpansive Mappings in CAT(0) spaces

Pim Sanboonsiri, Paiwan Wongsasinchai


In this paper, we introduce the modified algorithm in frame of a CAT(0) space for total asymptotically nonexpansive mapping and prove strong convergence. Moreover, we have numerical example for the proposed algorithm to compare speed of convergence among the existing iterative algorithm.
