浙大-西湖几何分析讨论班——Asymptotic stability of the Simons cone for the spherically symmetric timelike extremal hypersurfaces in Minkowski space

报告人：闫卫平教授（广西大学）时间：2023年12月19日（星期二）上午10:30-11:30 地点：海纳苑2幢202摘要：The Simons cone is known as a counter-example of Bernstein conjecture for the minimal surface equation. This celebrated minimal surface is a stationary solution of the timelike extremal hypersurface equation in higher dimension. In this talk, we introduce asymptotic stable of th...

浙大-西湖几何分析讨论班——Some results on the Hermitian-Yang-Mills ﬂow

报告人：张川静（中国科学技术大学）时间：2023年12月12日（星期二）上午10:30-11:30 地点：海纳苑2幢202摘要：In this talk, we consider the limiting property of the Hermitian-Yang-Mills ﬂow and introduce our recent works in the non-Kähler case. Then we give some applications. These works are joint with Zeng Chen, Chao Li and Professor Xi Zhang. 联系人：江文帅老师（wsjiang@zju.edu.cn)

Weighted geometric inequalities and applications

报告人: 韦勇教授（中国科学技术大学）时间: 2023年11月28号（星期二）10:30-11:30地点: 海纳苑2幢102 摘要：In this talk, we discuss some weighted geometric inequalities for domains in space forms. First, we consider a weighted isoperimetric inequality which compares boundary momentum, boundary area and enclosed volume for a star-shaped and mean convex domain in the Euclidean space. As an ap...

浙大-西湖几何分析讨论班—Existence of four minimal spheres in S^3 with a bumpy metric

报告人：王志超（复旦大学）时间：2023年11月14日（星期二）上午10:30-11:30 地点：海纳苑2幢202摘要：In this talk, we show that in the three dimensional sphere with a bumpy metric or a metric with positive Ricci curvature, there exist at least four distinct embedded minimal two-spheres. This confirms a conjecture of S. T. Yau in 1982 for bumpy metrics and metrics with positive Ricci curvature. The...

几何分析讨论班—Dynamical Iitaka dimension and fibration

报告人：孟晟（华东师范大学）时间：2023年10月24日（星期二）上午10:30-11:30 地点：海纳苑2幢105摘要： In this talk, I shall introduce our new Dream Building Blocks conjecture. This is a conjecture on the building blocks of surjective endomorphisms of projective varieties. I shall mainly focus our new technique on the dynamical Iitaka fibration. Applications will be discussed on several ari...

几何分析讨论班--Rigidity theorems about Q-curvature

报告人：李明翔博士（南京大学）时间：2023年10月10日（星期二）上午10:30-11:30 地点：海纳苑2幢105摘要：In this talk, we will introduce some rigidity theorems on complete and conformally flat manifolds with help of Q-curvature. We introduce a new volume entropy to give a sufficient and necessary condition for the ”normal” metric. Meanwhile, with help of geometric measure theory, we give a di...
