Abstract: In this talk I will discuss some recent results regarding the optimality of polygonal shapes for some nonlocal variational problems. In the first part of the talk I will discuss the minimization of an energy functional given by the sum of a crystalline perimeter and a nonlocal interaction of Riesz type: I will exhibit a class of polygonal Wulff shapes which uniquely minimize these energies in the small volume regime. In the second part of the talk I will discuss the optimality of regular polygons for nonlocal energies of generalized Riesz-type in the class of polygons with a fixed number of sides and fixed area, as well as their characterization as unique stationary point. These results are joint work with R. Cristoferi and I. Topaloglu.
