Optimality and Duality for Minmax Problems Involving Arcwise Connected and Generalized Arcwise Connected Functions

In this paper, we establish necessary optimality conditions for a static minmax programming problem of the form: min maxf x, y. subject to g x.O0, ygY in terms of the right derivatives of the functions with respect to the same arc. Various theorems giving sufficient optimality conditions are proved. A Mond-Weir type dual is proposed and duality results are established under arcwise connectedness and generalized arcwise connectedness assumptions
