Non-collapsing volume estimate for local K\"ahler metrics in big cohomology classes

Differential Geometry 2026-02-25 v2 Complex Variables

Abstract

We prove a uniform local non-collapsing volume estimate for a large family of singular metrics in the big cohomology classes, which are K\"ahler on an open Euclidean subset of the manifold. The key ingredient is a generalization of a mixed energy estimate for functions in the complex Sobolev space to the setting of big cohomology classes.
