Variation, polytopes and KE metrics on Q-Fano varieties - 朱小華 教授(北京大學)

作者:   來源:  時間:2020-01-10

題目:Variation, polytopes and KE metrics on Q-Fano varieties  

報告人:朱小華 教授(北京大學)

Abstract:

In this talk, we introduce a variation method to study the Kaehler-Einstein metrics (possibly singular)on Q-Fano compatifications of reductive Lie  groups. On such $Q$-Fano varieties, we can reduce the Euler-Langrange functional of KE metric equation to a reduced Ding-functional with a weighted Monge-Ampere measure for convex functions on the moment polytope. Then we will derive a similar criterion for the existence of KE metrics as on the smooth compatifications proved by Delcroix and LI-Zhou-Zhu.
