Wolfe E-duality for E-differentiable E-invex Vector Optimization Problems with Inequality and Equality Constraints

In this paper, the class of E-differentiable vector optimization problems with both inequality and equality constraints is considered. For such (not necessarily) differentiable vector optimization problems, The so-called scalar and vector Wolfe E-dual problems are defined for the considered E-differentiable multiobjective programming problem with both inequality and equality constraints and several E-dual theorems are established also under (generalized) E-invexity hypotheses.
