Abstract

We introduce two iterative algorithms for finding a common element of the set of fixed points of an asymptotically $k$-strict pseudo-contraction and the set of solutions of a mixed equilibrium problem in a Hilbert space. We obtain some weak and strong convergence theorems by using the proposed iterative algorithms. Our results extend and improve the corresponding results of Tada and Takahashi [16] and Kim and Xu [8, 9].

Keywords: mixed equilibrium problems, fixed point problems, iterative algorithm, asymptotically $k$-strict pseudo-contraction, Hilbert space
