A transcendental non-Archimedean Calabi–Yau Theorem with applications to the cscK problem

Published in arXiv, 2025

Joint with David Witt Nyström. In it we solve the non-Archimedean Monge-Ampère equation for compact Kähler manifolds, generalizing a result of Boucksom–Favre–Jonsson to the transcendental setting. This allows us to derive a valuative criterion for uniform K-stability for models. As a central application, we prove that this stability condition implies the existence of a unique constant scalar curvature Kähler metric.

A non-Archimedean theory of complex spaces and the cscK problem

Published in Advances in Mathematics, 2024

In this paper I construct a space of valuations attached to a compact complex manifold, that generalize the Berkovich analytification of a projective variety over \( \mathbf C \). As an application I get a sufficient algebraic condition for the existence of constant scalar curvature Kähler metrics on a given Kähler class on a Kähler manifold.
