Chern forms of hermitian metrics with analytic singularities on vector bundles

preprint2022arXivOpen access

Abstract

We define Chern and Segre forms, or rather currents, associated with a Griffiths positive singular hermitian metric hh with analytic singularities on a holomorphic vector bundle EE. The currents are constructed as pushforwards of generalized Monge-Ampère products on the projectivization of EE. The Chern and Segre currents represent the Chern and Segre classes of EE, respectively, and coincide with the Chern and Segre forms of EE and hh, where hh is smooth. Moreover, our currents coincide with the Chern and Segre forms constructed by the first three authors and Ruppenthal in the cases when these are defined.
