Viscosity Approximation Methods for a Family of Nonexpansive Mappings in CAT(0)‎ Spaces

Abstract EN

The purpose of this paper is using the viscosity approximation method to study the strong convergence problem for a family of nonexpansive mappings in CAT(0) spaces.

Under suitable conditions, some strong convergence theorems for the proposed implicit and explicit iterative schemes to converge to a common fixed point of the family of nonexpansive mappings are proved which is also a unique solution of some kind of variational inequalities.

The results presented in this paper extend and improve the corresponding results of some others.
