Title

Openness of K-semistability for Fano varieties

Abstract

Recently, the question of whether one can construct nicely behaved moduli spaces for Fano varieties using K-stability has attracted significant interest. More precisely, the Fano K-moduli Conjecture predicts that K-polystable Fano varieties with fixed volume and dimension form a projective good moduli space. In this talk, I will explain the proof of openness of K-semistability for Fano varieties which is one major step in the Fano K-moduli Conjecture. Our proof is a combination of valuative criterion for K-semistability due to Fujita and Li, boundedness of complements due to Birkar, and approximation techniques. This talk is based on joint work with Harold Blum and Chenyang Xu.
