Optimality conditions for vector equilibrium problems in normed spaces |
|
| Abstract: | 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. |
| Keywords: | vector equilibrium problems optimality conditions contingent epiderivative weakly efficient solution properly efficient solution |
