## Multiobjective programming under $$d$$-invexity.(English)Zbl 1027.90076

Summary: A generalization of convexity is considered in the case of a nonlinear multiobjective programming problem where the functions involved are nondifferentiable. By considering the concept of Pareto optimal solution and substituting $$d$$-invexity for convexity, the Fritz John type and Karush-Kuhn-Tucker type necessary optimality conditions and duality in the sense of Mond-Weir and Wolfe for nondifferentiable multiobjective programming are given.
