The purpose of this paper is to introduce and consider new hybrid proximal-type algorithms for finding a common element of the set E P of solutions of a generalized equilibrium problem, the set 𝐹 ( 𝑆 ) of fixed points of a relatively nonexpansive mapping 𝑆 , and the set 𝑇 1 0 of zeros of a maximal monotone operator 𝑇 in a uniformly smooth and uniformly convex Banach space. Strong convergence theorems for these hybrid proximal-type algorithms are established; that is, under appropriate conditions, the sequences generated by these various algorithms converge strongly to the same point in E P 𝐹 ( 𝑆 ) 𝑇 1 0 . These new results represent the improvement, generalization, and development of the previously known ones in the literature.
