报告摘要
If the delta invariant of a Fano manifold is greater than one, then it is K-stable and admits a KE metric. In this case, it admits no nontrivial holomorphic vector field. For a Fano manifold with nontrivial holomorphic vector fields, we will introduce a computable "delta" invariant, which characterizes its K-polystability.
