Relative uniform $K$-stability over models implies existence of extremal metrics

Differential Geometry 2026-04-09 v1 Algebraic Geometry

Abstract

We prove that an extremal metric on a polarised smooth complex projective variety exists if it is G\mathbb{G}-uniformly KK-stable relative to the extremal torus over models, extending a result due to Chi Li for constant scalar curvature K\"ahler metrics.
