Abstract: In this paper, a class of E-differentiable multiobjective programming problems with both inequality and equality constraints is considered. The so-called E-Karush-Kuhn-Tucker necessary optimality conditions are established for such nonsmooth vector optimization problems. Also, the sufficiency of these necessary optimality conditions are proved for E-differentiable multiobjective programming problems under (generalized) E-invexity hypotheses.
