Analytic torsion forms for fibrations by projective curves

Algebraic Geometry 2023-09-29 v2 Differential Geometry

Abstract

An explicit formula for analytic torsion forms for fibrations by projective curves is given. In particular one obtains a formula for direct images in Arakelov geometry in the corresponding setting. The main tool is a new description of Bismut's equivariant Bott-Chern current in the case of isolated fixed points.
