摘要:In this talk, I will investigate some fundamental properties of convex sets, convex cones, and convex functions in groups and semigroups. In particular, I will introduce the concept of quasi core of a convex set, which allows us to provide separation theorems between convex sets in groups where at least one of them has nonempty quasi core. I also analyze optimization problems defined on groups and semigroups and provide saddle point necessary or sufficient optimality conditions by considering suitable Lagrangian functions associated with the given problem. This is my joint work with Dr. Giandomenico Mastroeni.
