Generalized invexity and duality theories with multifunctions
Phạm Hữu Sách, Nguyen Dong Yen, B. D. Craven · Numerical Functional Analysis and Optimization · 1994
Some generalizations of invexity for multifunctions (pseudoinvex, pseudo-quasiinvex, quasi-strictly pseudoinvex …) are introduced and are used to extend the duality theories of Wolfe and Mond-Weir to optimization problems with multifunctions in the objective and in the constraints. Sufficiency results are also given.
