Bregman Projections and Parallel Extragradient Methods for Solving Multiple-sets Split Problems

In this paper, utilizing Bregman projections which are different from the sunny generalized nonexpansive retractions and generalized metric projection in Banach spaces, we introduce some new parallel extragradient methods for finding the solution of the multiple-sets split equilibrium problem and the solution of the multiple-sets split variational inequality problem in $p$-uniformly convex and uniformly smooth Banach spaces. Moreover, we introduce a $\Delta$-Lipschitz-type condition on the equilibrium bifunctions to prove strongly convergent of the generated iterates in parallel extragradient methods. To illustrate the usability of our results and also to show the efficiency of the proposed methods, we present some comparative examples with several existing schemes in the literature in finite and infinite dimensional spaces.
