On F-monotone operators and generalized strongly nonlinear variational inequalities

Abstract

In this paper we develop the existence theory of generalized strongly nonlinear variational inequality problem involving F-monotone operator in the setting of reflexive Banach spaces and Hausdorff topological vector spaces separately. Our results include Dugundji's and Granas's variational inequality in reflexive Banach spaces and Tan's variational inequality in topological vector spaces, respectively.
