报告摘要  Abstract

In this talk, we consider the stability problem of some kinds of elliptic relative equilibria which include elliptic relative equilibria of four-body problem with some small masses. By using the central configuration coordinate transformation and the Malov-type index, the conditions of linear stable of each kind solutions with respect to the parameters are given. We also show that the convexity of the corresponding central configurations play an import role in their linear stability analysis.
