报告摘要如下:
This is a joint work with Xiang Yu. Given an n-body central configuration, we find that there are exactly five ways to extend it to a non-collinear (n + 1)-body central configuration by adding one mass. It is necessary that the n-body central configuration must lie on a common circle or sphere. For the sufficient conditions, we find it crucial to measure the radius of the circle, sphere and one value determined by the total mass and the multiplier of the n-body central configuration. We also obtain a general result on the geometric property of the co-circular n-body central configurations, with which, we could classify all the extensions from four bodies to five. We then give complete answers to the questions raised by Hampton.
