Deskripsi
Let πΈ be a real reflexive and strictly convex Banach space with a uniformly GΓ’teaux differentiable norm. Let π={π(π‘)βΆπ‘β₯0} be a family of uniformly asymptotically regular generalized asymptotically nonexpansive semigroup of πΈ, with functions π’,π£βΆ[0,β)β[0,β). Let πΉβΆ=πΉ(π)=β©π‘β₯0πΉ(π(π‘))β β and πβΆπΎβπΎ be a weakly contractive map. For some positive real numbers π and πΏ satisfying πΏ+π>1, let πΊβΆπΈβπΈ be a πΏ-strongly accretive and π-strictly pseudocontractive map. Let {π‘π} be an increasing sequence in [0,β) with limπββπ‘π=β, and let {πΌπ} and {π½π} be sequences in (0,1] satisfying some conditions. Strong convergence of a viscosity iterative sequence to common fixed points of the family π of uniformly asymptotically regular asymptotically nonexpansive semigroup, which also solves the variational inequality β¨(πΊβπΎπ)π,π(πβπ₯)β©β€0, for all π₯βπΉ, is proved in a framework of a real Banach space.
