On Boundary Value Problems for Special Lagrangian Type Equations题目:On Boundary Value Problems for Special Lagrangian Type Equations报告人:邱国寰 副研究员 (中科院数学研究所)地点:致远楼101室时间:2025 年11 月13 日 14:00-15:30摘要:Special Lagrangian type equations form a class of geometric partial differential equations that characterize special Lagrangian submanifolds—minimal Lagrangian graphs in Euclidean space. These equations arise naturally in cali...邱国寰 副研究员 (中科院数学研究所)致远楼101室2025年11月13日 14:00-15:30

Dimer models and Beltrami Equation题目:Dimer models and Beltrami Equation报告人:钟晓 教授 (中山大学)地点:致远楼101室时间:2025年10月17日 8:30-9:30摘要: Scaling limits of random tilings present surprising geometric features under suitable boundary conditions and produce deterministic and disordered (also called frozen and liquid) limit configurations with interesting geometric properties. This talk will show how by methods ...钟晓 教授 (中山大学)致远楼101室2025年10月17日 8:30-9:30

Statistical Analysis of Conditional Group Distributionally Robust Optimizatio...题目:Statistical Analysis of Conditional Group Distributionally Robust Optimization with Cross-Entropy Loss报告人:郭子剑 教授(浙江大学)地点:致远楼108室时间: 2025年9月29日 10:30-11:30Abstract:In multi-source learning with discrete labels, distributional heterogeneity across domains poses a central challenge to developing predictive models that transfer reliably to unseen domains. We study ...郭子剑 教授(浙江大学)致远楼108室2025年9月29日 10:30-11:30

ALH Geometry and the Positive Energy Theorem题目:ALH Geometry and the Positive Energy Theorem报告人:张晓 研究员(中国科学院数学与系统科学研究院)地点:致远楼108室时间:2025年9月26日 18:25-20:15Abstract: In 1988, LeBrun constructed an ALE metric with negative mass. This provides the counterexample of Hawking-Pope's generalized positive action conjecture for the zero cosmological constant. In this talk, we study the analougous proble...张晓 研究员(中国科学院数学与系统科学研究院)致远楼108室2025年9月26日 18:25-20:15

Morse Theory and Moduli Spaces of Self-Avoiding Polygonal Linkages题目:Morse Theory and Moduli Spaces of Self-Avoiding Polygonal Linkages报告人:周泽 教授(深圳大学)地点:宁静楼117室时间:2025年9月21日 星期日 10:30-11:30摘要: We show that a $d$-dimensional smooth manifold $M$ is diffeomorphic to $\mathbb R^d$ if it admits a Lyapunov-Reeb function, i.e., a smooth map $f:M\to \mathbb R$ that is proper, lower-bounded, and has a unique critical point. By cons...周泽 教授(深圳大学)宁静楼117室2025年9月21日 星期日 10:30-11:30

2-Regular Points in Ricci Limit Spaces题目:2-Regular Points in Ricci Limit Spaces报告人:陈丽娜 副教授(南京理工大学)地点:致远楼103室时间:2025年7月28日 9:30-10:30Abstract:In this note, we will show that if a measured Gromov-Hausdorff limit space of a sequence of Riemannian manifolds with lower Ricci curvature bound contains a 2-regular point which lies in the interior of a geodesic, then it is 2-rectifiable. And we will also g...陈丽娜 副教授(南京理工大学)致远楼103室2025年7月28日 9:30-10:30
