\(D\)-invexity and optimality conditions. (English) Zbl 0755.90074
Summary: A generalization of convexity, called \(d\)-invexity, is introduced. Substituting \(d\)-invex for convex, we get some optimality conditions for nondifferentiable multiobjective programming. The application is demonstrated by an example.
