We construct weight functions on the Berkovich analytification of a variety over a trivially-valued field of characteristic zero, and this leads to the definition of the Kontsevich-Soibelman skeletons and the essential skeletons of pairs. We prove that the weight functions determine a metric on the pluricanonical bundles which coincides with Temkin's canonical metric in the smooth case. The weight functions are defined in terms of log discrepancies, which makes the Kontsevich-Soibelman and… Expand
The Frobenius structure theorem for affine log Calabi-Yau varieties containing a torus
We show that the naive counts of rational curves in any affine log Calabi-Yau variety $U$, containing an open algebraic torus, determine in a surprisingly simple way, a family of log Calabi-YauExpand
Berkovich log discrepancies in positive characteristic
We introduce and study a log discrepancy function on the Berkovich analytifications of schemes in positive characteristic that shares many properties with the analogue in characteristic zero. WeExpand
P=W conjectures for character varieties with symplectic resolution
We establish P=W and PI=WI conjectures for character varieties with structural group $\mathrm{GL}_n$ and $\mathrm{SL}_n$ which admit a symplectic resolution, i.e. for genus 1 and arbitrary rank, andExpand

The essential skeleton of a degeneration of algebraic varieties
In this paper, we explore the connections between the Minimal Model Program and the theory of Berkovich spaces. Let $k$ be a field of characteristic zero and let $X$ be a smooth and projectiveExpand
Motivic Serre invariants, ramification, and the analytic Milnor fiber
We show how formal and rigid geometry can be used in the theory of complex singularities, and in particular in the study of the Milnor fibration and the motivic zeta function. We introduce theExpand
Weight functions on non-archimedean analytic spaces and the Kontsevich-Soibelman skeleton
We associate a weight function to pairs consisting of a smooth and proper variety X over a complete discretely valued field and a differential form on X of maximal degree. This weight function is aExpand
Uniform K-stability, Duistermaat-Heckman measures and singularities of pairs
The purpose of the present paper is to set up a formalism inspired from non-Archimedean geometry to study K-stability. We first provide a detailed analysis of Duistermaat-Heckman measures in theExpand
The dual complex of Calabi–Yau pairs
A log Calabi–Yau pair consists of a proper variety X and a divisor D on it such that $$K_X+D$$KX+D is numerically trivial. A folklore conjecture predicts that the dual complex of D is homeomorphic toExpand

Metrization of Differential Pluriforms on Berkovich Analytic Spaces
We introduce a general notion of a seminorm on sheaves of rings or modules and provide each sheaf of relative differential pluriforms on a Berkovich k-analytic space with a natural seminorm, calledExpand

In this article, we consider Nakajima quiver varieties from the point of view of symplectic algebraic geometry. We prove that they are all symplectic singularities in the sense of Beauville andExpand
