Homotopy of Manifolds Stabilized by Projective Spaces题目:Homotopy of Manifolds Stabilized by Projective Spaces报告人:黄瑞芝 副研究员(中科院数学所)时间:2024年4月15日 10:00-11:00地点:致远楼101室Abstract: Connected sum of a manifold with a projective space is of special interest. For instance, in geometric topology, Kreck suggested to study the stable classification of smooth manifolds modulo a projective space summand.In this talk, we study ...黄瑞芝 副研究员(中科院数学所)致远楼101室2024年4月15日 10:00-11:00

The Isometric Immersion of Surfaces with Finite Total Curvature题目:The Isometric Immersion of Surfaces with Finite Total Curvature报告人:韩青 教授(美国诺特丹大学、北京大学)时间:2024年4月2日15:30-16:30地点:致远楼101室Abstract: In this talk, we discuss the smooth isometric immersion of a complete simply connected surface with a negative Gauss curvature in the three- dimensional Euclidean space. For a surface with a finite total Gauss curvature and ap...韩青 教授(美国诺特丹大学、北京大学)致远楼101室2024年4月2日15:30-16:30

Selective Conformal Inference with False Coverage-Statement Rate Control题目:Selective Conformal Inference with False Coverage-Statement Rate Control姓名:任好洁 副教授 (上海交通大学)时间:2024年3月27日 10:00-11:00地点:致远楼108室Abstract:Conformal inference is a popular tool for constructing prediction intervals. We consider here the scenario of post-selection/selective conformal inference, that is prediction intervals are reported only for individuals selected...任好洁 副教授 (上海交通大学)致远楼108室2024年3月27日 10:00-11:00

The Quasi-Isometry Group of the Real Line cannot Act Effectively on the Line题目:The Quasi-Isometry Group of the Real Line cannot Act Effectively on the Line报告人:叶圣奎 副教授 (上海纽约大学)时间:2024年3月28日 星期四 9:30—10:30地点:致远楼108室摘要:We show that the group of orientation-preserving quasi-isometries of the real line is a left-orderable, non-simple group, but cannot act effectively on the real line by homeomorphisms. If time permits, we will discus...叶圣奎 副教授 (上海纽约大学)致远楼108室2024年3月28日 星期四 9:30—10:30

Symplectic Critical Surfaces and Related Evolution Equations题目:Symplectic Critical Surfaces and Related Evolution Equations报告人:孙俊 副教授 (武汉大学)时间:2023年3月21日 8:15-9:15地点:腾讯会议室摘要: In this talk, we will introduce a new family of functionals approaching to the existence of holomorphic curves in Kahler surface. We will study the properties of the critical points of the new functionals as well as the gradient flows. This is join...孙俊 副教授 (武汉大学)腾讯会议室2023年3月21日 8:15-9:15

The Neumann Problem of Special Lagrangian Type Equations题目:The Neumann Problem of Special Lagrangian Type Equations报告人:邱国寰 副研究员 (中科院数学研究所)时间: 2023年3月22日 9:00-10:00地点:腾讯会议室摘要: We study the Neumann problem for special Lagrangian type equations with critical and supercritical phases. These equations naturally generalize the special Lagrangian equation and the k-Hessian equation. By establishing uniform a priori e...邱国寰 副研究员 (中科院数学研究所)腾讯会议室2023年3月22日 9:00-10:00

Applications of Integral Inequalities to the Calculus of Variations题目:Applications of Integral Inequalities to the Calculus of Variations报告人:Prof. Cheung Wingsum (香港大学)时间:2023年3月21日 10:00-11:00地点:致远楼101室摘要A typical calculus of variations problem is to optimize a functional of functions of one variable. The classical approach is to solve the associated Euler-Lagrange equation. In case the functional involves higher order derivatives ...Prof. Cheung Wingsum (香港大学)致远楼101室2023年3月21日 10:00-11:00
