Bott-Chern characteristic classes of blow-ups

Algebraic Geometry 2024-08-07 v1 Differential Geometry

Abstract

We prove a blow-up formula for Bott-Chern characteristic classes of compact complex manifolds. To this end, we establish a version of Riemann-Roch without denominators for the Bott-Chern characteristic classes. In particular, as an application, we study the behaviour of the Bott-Chern characteristic classes of the Iwasawa manifold under a blow-up transformation.
