Abstract：
In this talk, We give a classification of Gorenstein Fano equivariant compactifications of complex semisimple Lie groups with rank two, and determine which of them are equivariant K-stable and admit (singular) Kähler-Einstein metrics. As a consequence, we obtain several explicit examples of K-stable Fano varieties admitting (singular) Kähler-Einstein metrics. We also compute the greatest Ricci lower bounds, equivalently the delta invariants for K-unstable varieties. This gives us three new examples on which each solution of the Kähler-Ricci flow is of type II. This is based on the joint work with Jae-Hyouk Lee and Kyeong-Dong Park.
