Hodge cohomology on blow-ups along subvarieties

Algebraic Geometry 2022-03-01 v2

Abstract

We establish a blow-up formula for Hodge cohomology of locally free sheaves on smooth proper varieties over an algebraically closed field of positive characteristic. For this, we introduce a notion of relative Hodge sheaves and study their behavior under blow-ups along smooth centers. In particular, as an application, we study the blow-up invariance of the E2E_2-degeneracy of the Hochschild--Kostant--Rosenberg spectral sequence for smooth proper varieties.
