Vector optimization model has found many important applications in decision making
problems such as those in economics theory, management science, and engineering design …

Convex and non-convex fuzzy mappings are well known to be important in the research of
fuzzy optimization. Symmetry and the idea of convexity are closely related. Therefore, the …

This paper gives necessary and sufficient conditions for We do so by introducing a class of
transfer continuities which characterize the essence of topological structures of functions …

In this paper, we extend the auxiliary principle technique to study a class of generalized set-
valued strongly nonlinear mixed variational-like inequalities. We prove the existence of a …

In this paper, we use the auxiliary principle technique to prove the existence of a solution of
some new classes of variational inequalities, which are called the generalized mixed …

In this paper, we deal with the following quasi-equilibrium problem: given a nonempty
subset C of a topological vector space X, a nonempty set D, two functions T: C→ D, f: X× D→ …

In this article, we study the parametric vector quasi-equilibrium problem (PVQEP). We
investigate existence of solution for PVQEP and continuities of the solution mappings of …

In this paper, we introduce and study some new classes of multivalued variational
inequalities. These classes are more general and include the previously known classes of …

In this paper, we introduce a new class of vector quasi-equilibrium problems with set-valued
maps. Almost all the vector equilibrium models of the Blum-Oettli type in the literature are …

In this paper, we present results that use Himmelberg's fixed point theorem to highlight
substantive trade-offs between compactness, continuity and convexity postulates in the …
