摘 要:

The N-body problem is one classical topic in dynamical system. In the N-body problem, the periodic solutions which can be written down are so rare when $N$ is greater than 3. The elliptic relative equilibria are among them. The system is called the restricted four-body problem if there are three primaries and one zero-mass body. In this talk, I will introduce elliptic relative equilibria of restricted four-body problem and discuss our recent results on their linear stability via the Maslov index theory. This is a joint work with Prof. Qinglong Zhou.
