Convergence analysis for variational inequalities and fixed point problems in reflexive Banach spaces
Abstract In this paper, using a Bregman distance technique, we introduce a new single projection process for approximating a common element in the set of solutions of variational inequalities involving a pseudo-monotone operator and the set of common fixed points of a finite family of Bregman quasi-...
