説明
We give a purely algebro–geometric proof that if the α-invariant of a Q-Fano variety X is greater than dim X/(dim X+1), then(X, OX(-KX))is K-stable. The key of our proof is a relation among the Seshadri constants, the α-invariant and K-stability. It also gives applications concerning the automorphism group.
