Abstract
The key idea behind solving well known applicable problems is
to reformulate the problems as finding a fixed point of a suitably
defined mapping. The theory of variational inequalities and
equilibrium problems involving some operators with monotonicity
conditions have received remarkable development with several
methods suggested for solving them. Efforts have significantly
been made in approximating fixed points and h-fixed point of
(possibly set valued, nonlinear) mapping in different suitable
real Banach spaces. The intersections of these four streams;
functional-analytic fixed and h- fixed point theories, and the
mathematics of variational and equilibrium problems have not
been well researched. The purpose of this paper is to construct an
algorithm for the approximation of the common solution of the set
of h-fixed points of a h-pseudo-contractive mapping; set of fixed
point of a Bregman quasi mapping; set of solution of equilibrium
problems for pseudomonotone mapping and the set of variational
inequality problem for Lipschitz monotone mapping which leads
to a prove of strong convergence theorem for it in Banach spaces.
