Title: Crown Central Configurations

Speaker:  Antonio Carlos Fernandes

Affiliation: Universidade Federal de Itajubá

Abstract: In this talk we present some results about (K,N)-Crown Central Configurations, which are formed by K concentric regular N-polygons in the plane. If the configuration is nested (the polygons are homothetic) we show conditions for existence of solutions with positive masses. Also in the case twisted (each polygon is rotated π/N referred to the inner one). We also present a numerical result without symmetry in the angles.
