In this paper, we prove the openness of K-semistability in families of log Fano pairs by showing that the stability threshold is a constructible function on the fibers. We also prove …

In this paper, we consider the CM line bundle on the K-moduli space, ie, the moduli space parametrizing K-polystable Fano varieties. We prove it is ample on any proper subspace …

We give an algebraic proof of the equivalence of equivariant K-semistability (resp. equivariant K-polystability) with geometric K-semistability (resp. geometric K-polystability) …
Algebraic varieties are shapes defined by polynomial equations. Smooth Fano threefolds are a fundamental subclass that can be thought of as higher-dimensional generalizations of …
We develop the moduli theory of boundary polarized CY pairs, which are slc Calabi-Yau pairs $(X, D) $ such that $ D $ is ample. The motivation for studying this moduli problem is to …
Let X be any Q Q-Fano variety and Aut (X) _0 Aut (X) 0 be the identity component of the automorphism group of X. Let GG be a connected reductive subgroup of Aut (X) _0 Aut (X) 0 …
We establish an algebraic approach to prove the properness of moduli spaces of K- polystable Fano varieties and reduce the problem to a conjecture on destabilizations of K …
Abstract The Chow–Mumford (CM) line bundle is a functorial line bundle on the base of any family of klt Fano varieties. It is conjectured that it yields a polarization on the moduli space …
