A pullback operation on a class of currents

Algebraic Geometry 2022-12-02 v4 Complex Variables

Abstract

For any holomorphic mapping f ⁣:XYf\colon X\to Y between a complex manifold XX and a complex Hermitian manifold YY we extend the pullback ff^* from smooth forms to a class of currents. We provide a basic calculus for this pullback and show under quite mild assumptions that it is cohomologically sound. The class of currents we consider contains in particular the Lelong current of any analytic cycle. Our pullback depends in general on the Hermitian structure of YY but coincides with the usual pullback of currents in case ff is a submersion. The construction is based on the Gysin mapping in algebraic geometry.
