Optimality conditions for vector equilibrium problems in normed spaces
Bo Chang, Xun Hua Gong · Optimization · 2010
By using the concepts of contingent epiderivative, radial epiderivative, Clarke tangent epiderivative and Y-epiderivative, we present necessary and sufficient conditions for the weakly efficient solution, the Henig efficient solution, and the globally proper efficient solution, respectively, to vector equilibrium problems with constraints.
