Abstract

Let K be a nonempty closed convex subset of a real reflexive Banach spaces E that has weakly continuous duality mapping for some guage Let be a finite family of generalized asymptotically quasi-nonexpansive mappings with which is a sunny nonexpansive retract of K with Q, a nonexpansive retraction. For let be generated by the algorithm where is a contraction mapping, and let be a sequence satisfying certain conditions. Suppose that satisfies condition (A). Then, it is proved that converges strongly to a common fixed point of a finite family Moreover, is the unique solution in F to a certain variational inequaliy.

Keywords

generalized asymptotically quasi-nonexpansive mappings, weakly continuous duality mappings.
