K-stability for varieties with a big anticanonical class

Algebraic Geometry 2026-05-27 v3 Differential Geometry

Abstract

We extend the algebraic K-stability theory to projective klt pairs with a big anticanonical class. While in general such a pair could behave pathologically, it is observed in this note that K-semistability condition will force them to have a klt anticanonical model, whose stability property is the same as the original pair.
