Optimality conditions for \(\epsilon\)-vector equilibrium problems
Summary: By virtue of the separation theorem of convex sets, a necessary condition and a sufficient condition for \(\epsilon\)-vector equilibrium problem with constraints are obtained. Then, by using the Gerstewitz nonconvex separation functional, a necessary and sufficient condition for \(\epsilon\)-vector equilibrium problem without constraints is obtained.
