题目：Toric Einstein 4-manifolds with nonnegative sectional curvature     报告人：刘天约教授(北京大学)   摘要：We study some interesting curvature properties of Einstein 4 manifolds in the presence of symmetry. In particular we show that the only T^...

题目：Spiral minimal products     报告人：张永胜教授(350vip葡京新集团登入网址)   摘要：We discover a structure -- spiral minimal product (SMP) among minimal submanifolds in unit Euclidean spheres. For a pair of C-totally real minimal submanifolds f1 and f2, their...

题目：Anisotropic capillary hypersurfaces in a wedge 报告人：马辉教授(清华大学) 摘要：Alexandrov's Soap Bubble Theorem is a fundamental result in differential geometry. In this talk we establish  Minkowski formulae and a Heintze-Karcher type inequality for ...

题目：Tangent cones of asymptotically flat 4-manifolds with cone structure 报告人：李明阳教授(美国加州大学伯克利分校)       摘要：It was proved by Petrunin and Tuschmann around 2000 that for an asymptotically flat 4-manifold whose tangent cone is a metric co...

动力系统讨论班-短课程 题目：Feynman Graph Integrals and Configuration Spaces 报告人：王明浩博士（Boston University） 摘要：In this mini-course, I will introduce Feynman graph integrals from topological and holomorphic quantum field theories. For ap...

题目：非交换几何简介与非交换空间分类 报告人：龚贵华教授 (美国波多黎哥大学) 摘要：紧Hausdorff 空间以及此类空间之间的连续映射对应于含幺元交换C* 代数以及这些代数之间的同态映射。A. Connes 首先发现有很多几何拓扑对象可以对应于非交换的C*代数，因而开创了非交换几何（拓扑）的新领域。在这个报告中，我们将从一个角度（非交换商空间）来窥探非交换几何的思想，并简要介绍我本人及合作者在C*代数（非交换空间）分类方面的工作。 报告人简介：龚...

题目：New Monge-Ampere type PDEs and canonical metrics on Hopf surfaces 报告人：方浩（美国爱荷华大学） 摘要：We report some recent joint work with Josh Jordan in Hermitian geometry. Hopf surfaces and Inoue surfaces of type M are important type VII examp...

题目：Twisted intertwining operators and tensor products of (generalized) twisted modules 报告人：黄一知教授(罗格斯大学) 摘要：We introduce a more general notion of twisted intertwining operator than the one introduced by the speaker in 2017. Using t...

题目：Deep neural networks for survival analysis: a few recent developments 报告人：Shuangge Ma (Yale University) 摘要：Most of the existing data analysis techniques are based on regression models and corresponding likelihood (estimating ...

题目：Recent Progress in Singular Flows 报告人：杨帆 助理教授 (Wake Forest University) 摘要：We will discuss recent progress in the theory of singular flow. More specifically, we will focus on the ergodic theory of smooth singular star flows. Such...
