Singular constant scalar curvature Kähler metrics

Speaker：Kai Zheng (Tonji University)

Schedule： Tue/Thu/Fri, 3:20 - 4:50PM 2021-10-26/28/29

Venue：Zoom Meeting ID: 816 4977 5126； Passcode: Kahler

Description

The first lecture will be quick background on the constant scalar curvature Kähler (cscK) problem [1-5] and the general setup on cscK cone metrics mainly from the paper [6]. The second lecture will lead to the existence results for the cscK cone metrics, and more general, the singular cscK metrics [7]. After all these preparation, the third lecture will present results on geometric applications, including links to log K stabilities and properties of the cscK cone path etc [8].

Prerequisite

Basic knowledge of differential and Kähler geometry including Kähler metric, scalar curvature, cone singularities,...
