数学科学学院学术报告Discontinuous Galerkin Methods for Fourth Order Variational Inequality崔金涛暨南大学报告时间：2025年11月14日 星期五 下午16：00-17：00报告地点：沙河校区E806报告摘要： In this work we study a family of discontinuous Galerkin methods and other methods for the displacement obstacle problem of Kirchhoff plates on convex polyhedral domains, which are characterized as fourth order ...
数学科学学院学术报告Wall crossing for K-moduli周楚宇（厦门大学）时间：2025-11-11 18:00-19:00（周二）地点：（线上）腾讯会议：637-499-769 摘要：In this talk, we will survey the recent progress on the wall crossing of K-moduli, with an emphasize on the non-proportional setting. In particular, we will prove the existence of the finite semi-algebraic chamber decomposition theorem to control the vari...
