Finite generation for valuations computing stability thresholds and applications to K-stability

Y Liu, C Xu, Z Zhuang - Annals of Mathematics, 2022 - projecteuclid.org
We prove that on any log Fano pair of dimension n whose stability threshold is less than
n+1n, any valuation computing the stability threshold has a finitely generated associated …

A variational approach to the Yau–Tian–Donaldson conjecture

R Berman, S Boucksom, M Jonsson - Journal of the American Mathematical …, 2021 - ams.org
We give a variational proof of a version of the Yau–Tian–Donaldson conjecture for twisted
Kähler–Einstein currents, and use this to express the greatest (twisted) Ricci lower bound in …

Uniform K-stability, Duistermaat–Heckman measures and singularities of pairs

S Boucksom, T Hisamoto, M Jonsson - Annales de l'Institut Fourier, 2017 - numdam.org
The purpose of this paper is to set up a formalism inspired by non-Archimedean geometry to
study K-stability. We first provide a detailed analysis of Duistermaat–Heckman measures in …

Thresholds, valuations, and K-stability

H Blum, M Jonsson - Advances in Mathematics, 2020 - Elsevier
Let X be a normal complex projective variety with at worst klt singularities, and L a big line
bundle on X. We use valuations to study the log canonical threshold of L, as well as another …

K-polystability of Q-Fano varieties admitting Kähler-Einstein metrics

RJ Berman - Inventiones mathematicae, 2016 - Springer
It is shown that any, possibly singular, Fano variety X admitting a Kähler-Einstein metric is K-
polystable, thus confirming one direction of the Yau-Tian-Donaldson conjecture in the …

Openness of K-semistability for Fano varieties

H Blum, Y Liu, C Xu - Duke Mathematical Journal, 2022 - projecteuclid.org
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 …
