Local Cohomological Defect and a Conjecture of Mustata-Popa

Algebraic Geometry 2026-02-06 v1

Abstract

We prove a general result on the depth of Du Bois complexes of a singular variety. We apply it to prove a conjecture of Mustata-Popa and to study the local cohomological defect, extending results of Ogus and Dao-Takagi over the complex numbers.
