New Mixed Equilibrium Problems and Iterative Algorithms for Fixed Point Problems in Banach Spaces

الملخص EN

We first introduce a new mixed equilibrium problem with a relaxed monotone mapping in Banach spaces and prove the existence of solutions of the equilibrium problem.

Then we introduce a new iterative algorithm for finding a common element of the set of solutions of the equilibrium problem and the set of fixed points of a quasi-ϕ-nonexpansive mapping and prove some strong convergence theorems of the iteration.

Our results extend and improve the corresponding ones given by Wang et al., Takahashi and Zembayashi, and some others.
