（9月28日）Heat kernel estimate and regularity of Ricci-harmonic flow

题目: Heat kernel estimate and regularity of Ricci-harmonic flow报告人：吴国强（浙江理工大学）时间：9月28日（周四）上午10:30-11:30  地点：工商楼4楼报告厅摘要:In this talk we discuss Ricci-harmonic flow on which the scalar curvature is bounded. At first, we establish a time derivative bound for solution to the heat equation, based on this, we derive the distance distortion estimate and the exi...

(9月21日）Uniqueness of stable free boundary CMC hypersurfaces in a ball

报告人：王国芳 教授（Freiburg University）Title： Uniqueness of stable free boundary CMC hypersurfaces in a ballAbstract: In this talk we will present a solution of a longstanding openproblem: Any stable free boundary CMC hypersurfaces in a ball are umbilic.One of crucial ideas is a new weighted Minkowski identity for free boundary hypersurfaces.Our proof works also for capillary hypersurfaces in ...

（9月19日）Iteration at the Boundary of Newton's Method

Title: Iteration at the Boundary of Newton's MethodSpeaker: Hongming Nie（Indiana University-Bloomington）Time: 1:30-2:30PM, September 19 (周二), 2017; 工商楼 200-9Abstract: Let NM_d be the space of degree d>2 Newton's method. We study the dynamical behaviors as maps approach to the boundary of NM_d. We prove that for a given holomorphic family of degree d Newton'...

(9月15日）On the structure of cyclotomic nilHecke algebras

报告题目： On the structure of cyclotomic nilHecke algebras报告人：胡峻 教授摘要： In this talk we shall consider the structure of the cyclotomic nilHecke Hecke algebras $/HH_{/ell,n}^{(0)}$, where $/ell,n/in/N$. We construct a monomial basis for $/HH_{/ell,n}^{(0)}$ which verifies a conjecture of Mathas. We show that the graded basic algebra of $/HH_{/ell,n}^{(0)}$ is commutative and hence isomor...
