1110BCOV invariants for Borcea-Voisin threefolds

中心:可积性以及与发散量的关系

(曹锡华数学论坛)

讲座题目:Centers: their integrability and relations with the divergence

主讲人:Jaume Llibre教授

主持人:刘兴波 副教授

开始时间:2015-11-1011:00-11:50

讲座地址:闵行校区数学楼126会议室

主办单位:数学系 科技处

报告人简介:Jaume Llibre教授,Universitat Autonoma de Barcelona(巴塞罗那自治大学)。西班牙皇家科学院院士,担任多个国际知名杂志主编和编委。在动力系统定性理论、分支理论等方面做出一些很好的工作,尤其在Hilbert第十六问题的相关研究中做了许多创新性的工作,其研究成果被国内外动力系统界专家学者广泛引用。

报告内容简介:

We shall recall briefly how can be the local phase portraits of the equilibrium points of an analytic differential system in the plane, and we shall put our attention in the centers. First in the kind of integrability of the different types of centers, and after in the focus-center problem, i.e. how to distinguish a center from a focus. This is a difficult problem which is not completely solved. We shall provide some new results using the divergence of the differential system.
