几何与拓扑讨论班——A characterization of uniruled Kaehler manifolds

报告人：Wenhao Ou，Institute of Mathematics, Chinese Academy of Sciences时间：2025年3月3日，16:45-17:35地点：紫金港校区海纳苑2幢204室摘要：We adapt Bost's algebraicity characterization to the situation of a germ in a compact Kaehler manifold. As a consequence, we extend the algebraic integrability criteria of Campana-Paun and of Druel to foliations on compact Kaehler manifolds. As an ap...

浙大-西湖几何分析讨论班——Construction of Morse Flow Lines between Self-expanders

报告人：陈乐天（University of Tennessee, Knoxville）时间：2025年1月6日（星期一），下午4:00-5:00地点：海纳苑2幢203摘要：One of the central questions in the study of mean curvature flow (MCF) is to determine whether one can flow past singularities. For asymptotically conical singularities, self-expanders model the potential continuations of MCFs past singularities. However, due to ...

浙大-西湖几何分析讨论班——Uniqueness of Kahler-Ricci Flow Limit

报告人：张州教授（悉尼大学）时间：2024年12月26日（星期四），下午3:00-4:00地点：海纳苑2幢102摘要：we discuss the fundamental/elementary problem on the uniqueness of Kahler-Ricci flow limit. The low regularity consideration is particularly convenient. There is also motivation from more recent study on the singularity type. Accidentally, what we’ve confirmed for the finite and infi...

浙大-西湖几何分析讨论班——Quantitative geometric inequalities in $\mathbb R^n$: Power growth other than 2

报告人：张翼（中科院）时间：2024年12月17日（星期二），下午4:00-5:00地点：海纳苑2幢206摘要：In the stability of geometric inequalities, usually one gets a growth with power $2$ as a lower bound for the difference of energy. For example, a remarkable result by Fusco, Maggi, and Pratelli says that, for any set of finite perimeter $E \subset \mathbb{R}^n$ with $|E| = |B|$ and a baryc...

浙大-西湖几何分析讨论班——A class of projectively flat Finsler metrics

报告人：莫小欢教授（北京大学）时间：2024年10月17日（周四）16：00-17:00地点：海纳苑2幢106摘要：Projectively flat Finlser metrics on a convex domain ${U}$ in $\mathbb{R}^n$ are regular solutions to Hilbert's Fourth Problem. In this lecture, we discuss projectively flat Finlser metrics on ${U}$. We find equations that characterize these metrics with weakly orthogonal inv...

几何分析讨论班——Effects of some new free boundary conditions on the nonlocal KPP equation with free boundary

报告人：杜一宏（澳大利亚科学院院士，澳大利亚新英格兰大学教授）时间：2024年9月18日，下午4:00-5:00地点：海纳苑2幢206室摘要：I will report some recent results on the nonlocal reaction diffusion equation $u_t-dL[u]=f(u)$ with a KPP type reaction term $f(u)$ over a changing interval $[g(t), h(t)]$, viewed as a model for the spreading of a species with population range $[g(t), h(t)]$ and density $u(t,x)...

浙大-西湖几何分析讨论班——The Monge-Ampere equation in convex polygonal domains

报告人：沈伟明教授（首都师范大学）时间： 2024年9月4日，10:30-11:30地点：海纳苑2幢101摘要： I will talk about the existence and regularity of solutions for the Monge-Ampere equation in convex polygonal domains. This is based on joint works with Genggeng Huang.联系人：江文帅（wsjiang@zju.edu.cn)

浙大-西湖几何分析讨论班——A rigidity result for ancient Ricci flows

报告人：张旗教授（加利福尼亚大学河滨分校）时间： 2024年9月6日，14:00-15:00地点：海纳苑2幢101摘要： Using the sharp log Sobolev functional (log entropy), we prove a qualitatively sharp rigidity result for ancient Ricci flows without sign condition on the curvatures. The result is also related to the backward limit problem of type II ancient Ricci flows.联系人：江文帅（wsjiang@zju.edu.cn)
