We consider parametric primal and dual Ky Fan inequalities in metric linear spaces. Sufficient conditions for Hölder continuity of solutions are established. Many examples are provided to illustrate the essentialness of the imposed assumptions and advantages of the results over existing ones....

In this paper, the notion of weak sharp minima is employed to the investigation of set-valued vector variational inequalities. The gap function [phi]T for set-valued strong vector variational inequalities (for short, SVVI) is proved to be less than the gap function [phi]T for set-valued weak...

The paper deals with a stability of multiobjective stochastic programming problems in which objective functions are in the form of mathematical expectation of functions depending on a random element and a constraints set is deterministic. The stability is investigated with respect to a...
