Hybrid Extragradient Iterative Algorithms for Variational Inequalities, Variational Inclusions, and Fixed-Point Problems

Journal of Applied Mathematics, 2012
We investigate the problem of finding a common solution of a general system of variational inequalities, a variational inclusion, and a fixed-point problem of a strictly pseudocontractive mapping in a real Hilbert space.

An extragradient-type method for solving nonmonotone quasi-equilibrium problems [PDF]

, 2017
In this paper, a quasi-equilibrium problem with a nonmonotone bifunction is considered in a finite-dimensional space. The primary difficulty with this problem is related to the fact that one must simultaneously solve a nonmonotone equilibrium problem and

Strong convergence of a hybrid method for pseudomonotone variational inequalities and fixed point problems

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this paper, we suggest a hybrid method for finding a common element of the set of solution of a pseudomonotone, Lipschitz-continuous variational inequality problem and the set of common fixed points of an infinite family of nonexpansive mappings.
