Abstract:

The purpose of this paper is to investigate a viscosity iterative algorithm based on a generalized contraction for finding a common element of the set of solutions of a general variational inequality problem for two inverse-strongly accretive mappings and the set of common fixed points for infinite strict pseudo-contractions in q-uniformly smooth and uniformly convex Banach spaces. Strong convergence theorems are proved under some appropriate conditions. The results obtained in this paper improve and extend many recent ones announced by many others in this literature.

Key words: Fixed point, Variational inequality, Strong convergence, Pseudocontraction, Banach space
