A dual generalization of convex functions

As it is well known, the convexity property of a function may be described by the quasiconvexity property of all "the dual perturbations" of this function. If we consider the "dual perturbation" only in a subset \(M\subset X^{\ast}\) we obtain a general class of functions called...
