Abstract

The purpose of this paper is to introduce and consider a new accelerated hybrid shrinking projection method for finding a common element of the set \(EP \cap F\) in reflexive Banach spaces, where \(EP\) is the set of all solutions of a generalized equilibrium problem, and \(F\) is the common fixed point set of finite uniformly closed families of countable Bregman quasi-Lipschitz mappings. It is proved that the sequence generated by the accelerated hybrid shrinking projection iteration, converges strongly to the point in \(EP \cap F,\) under some conditions. This result is also applied to find the fixed point of Bregman asymptotically quasi-nonexpansive mappings. It is worth mentioning that, there are multiple projection points from the multiple points in the projection algorithm. Therefore the new projection method in this paper can accelerate the convergence speed of iterative sequence. The new results improve and extend the previously known ones in the literature.
