题目：Relative equilibria in spaces of constant curvature
报告人： Ernesto Perez-Chavela教授（Instituto Tecnologico Autonomo de Mexico）
摘要：The curved N-body problem is a generalization of the classical Newtonian N-body problem to spaces with constant curvature K, in this talk we will consider the two dimensional case. Using the cotangent potential as a generalization of the Newtonian one, we describe some especial kind of periodic orbits where the mutual distances among the particles remain constant for all time, called relative equilibria. We classify these orbits for N = 2; 3 and study the linear stability of some of them.
