Strongly (E,F)-convexity with applications to optimization problems
strongly E-convex sets
strongly E-convex functions
strongly (E
F)-convex sets
strongly (E
F)-convex functions
In this paper, a new class of nonconvex sets and functions called strongly -convex sets and strongly -convex functions are introduced. This class is considered as a natural extension of strongly -convex sets and functions introduced in the literature. Some basic and differentiability properties related to strongly -convex functions are discussed. As an application to optimization problems, some optimality properties of constrained optimization problems are proved. In these optimization problems, either the objective function or the inequality constraints functions are strongly -convex.
