Abstract

In this article, we consider the solutions of the system of generalized variational inequality problems in Banach spaces. By employing the generalized projection operator, the well-known Fan's KKM theorem and Kakutani-Fan-Glicksberg fixed point theorem, we establish some new existence theorems of solutions for two classes of generalized set-valued variational inequalities in reflexive Banach spaces under some suitable conditions.

  • 1 Introduction Let E be a Banach space, E* be the dual space of E, and let 〈·,·〉 denotes the duality pairing of E* and E

  • If E is a Hilbert space and K is a nonempty, closed and convex subset of E, it is well known that the metric projection operator PK : E ® K plays an important role in nonlinear functional analysis, optimization theory, fixed point theory, nonlinear programming, game theory, variational inequality problem, and complementarity problems, etc

  • Related to the variational inequalities, we have the problem of finding the fixed points of the nonexpansive mappings, which is the current interest in functional analysis
