中国科技大学祝书强副研究员应邀来我院做学术报告
2018年12月13日下午4：00，在重庆工商大学数学与统计学院90510会议室，中国科技大学数学科学学院祝书强副研究员应我院邓义杨博士邀请做了题为《On stacked central configurations》的学术报告。祝书强：中国科学技术大学数学科学学院特任副研究员。2010年毕业于四川大学数学学院， 2017年毕业于维多利亚大学，获博士学位。主要从事哈密尔顿动力系统，弯曲空间的N体问题的研究，主要研究文章发表在《Journal of Nonlinear Science》,《Journal of Mathematical Physics》，《Proceeding of American Mathematical Society》, 《Journal of Dynamical System and Differential Equations》， 《Discrete and Continuous Dynamical Systems》上。
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.
数学与统计学院统计和优化等学科的部分师生参加了学术报告会。报告结束后，参会人员对祝教授的精彩报告进行了热烈讨论。祝教授丰富的知识、深入浅出的报告给参会老师深刻的印象，特别是让参会人员对天体力学以及中心构型有了新的认识和较为深入的了解。
