Singularity Type for Kahler-Ricci Flow over Minimal Manifolds

报告人：张州教授（悉尼大学）时间：2023年9月18日（星期一）下午16:00-17:00 地点：海纳苑2幢102摘要： in this talk, we start by describing the history of the study on this Kahler-Ricci flow, usually considered as the easy-sign version. The degenerate setting has been the main interest for the past 2 decades, following Tian’s Program which was later elaborated as Analytic Minimal Model Prog...

Mimetic Finite Difference Method for Partial Differential Equations

TITLE: Mimetic Finite Difference Method for Partial Differential EquationsSpeaker: Professor Hu Xiaozhe (Tufts University, U.S.A.)ABSTRACT: Numerical simulation of partial differential equation (PDE) models is essential to understand complex applications in science and engineering. When developing discretization methods for solving these PDEs, it is essential to preserve the physica...

The order complex of cosets in a finite group

题目: The order complex of cosets in a finite group报告人: 孟沆洋（上海大学）时间：2023年9月8日上午9:00-11:00地点：紫金港校区海纳楼2幢203 摘要: In this talk, we will introduce some algebraic topology methods on studying the poset(=partial ordered set) of some cosets of a finite group. Let G be a finite group and X be a subgroup of G. We investigate the topological properties of poset C_X(G) o...
