This paper is devoted to the characterizations of the boundedness and nonemptiness of solution sets for set-valued vector equilibrium problems in reflexive Banach spaces, when both themapping and theâ€¦ (More)

In this paper, we study the solution stability of parametric weak Vector Variational Inequalities with set-valued and single-valued mappings, respectively. We obtain the lower semicontinuity of theâ€¦ (More)

In this paper, we establish the equivalence between the existence of zeros for set-valued mappings and the solvability of variational inequality, under some conditions involving the generalizedâ€¦ (More)

In this paper, we propose a new notion of â€˜exceptional family of elementsâ€™ for convex optimization problems. By employing the notion of â€˜exceptional family of elementsâ€™, we establish some existenceâ€¦ (More)
