Abstract

In this paper, we introduced a new extended extragradient iteration algorithm for finding a common element of the set of fixed points of a nonexpansive mapping and the set of solutions of equilibrium problems for a monotone and Lipschitz-type continuous mapping. And we show that the iterative sequences generated by this algorithm converge strongly to the common element in a real Hilbert space.

Keywords: equilibrium problems, monotone mapping, Lipschitz-type continuous, strong convergence, extragradient algorithm, nonexpansive mapping
