报告人简介: 段华贵,教授,博导,南开大学威尼斯人 副院长,“核心数学与组合数学”教育部重点实验室副主任,天津市数学会秘书长,“南开大学百名青年学科带头人培养计划”入选者。主要研究方向为非线性分析与动力系统,近年来在微分几何中的闭测地线与哈密顿系统的周期轨道等方面取得系统性的研究成果,论文发表在J. Diff. Geom.,Adv. Math.,Math. Z.,J. Funct. Anal.,J. Diff. Equ.,Calc. Var. & PDE等国际学术期刊上。
报告摘要: In this talk, I will introduce a generalized common index jump theorem. As applications, some multiplicity results of closed characteristics on a broad class of star-shaped hypersurfaces in $R^{2n}$ have been obtained. This is a joint work with Prof. Yiming Long, Hui Liu and Wei Wang.
