On sufficiency and duality for generalised quasicnvex nonsmooth programs
Shashi Kant Mishra · Optimization · 1996
For a nonsmooth multiobjective nonlinear program which involves inequality and equality constraints, Fritz John and Kuhn-Tucker type sufficient optimality conditions are obtained. Some duality theorems are also established for Mond-Weir type of duals. All results are given under generalized convexity assumptions.
