Abstract

Let F\mathcal{F} be a coherent sheaf on a complex variety XX that has a locally free resolution EE^{\bullet}. In [19], the authors constructed a pseudomeromorphic current whose support is contained in supp(E)supp(E^{\bullet}) that represents products of Chern classes of F.\mathcal{F}. In this paper, we show that their construction works for general de-Rham characteristic classes and then generalize it to represent products (in de-Rham cohomology) of characteristic forms of cohesive modules defined by Block. Finally, we state a corollary to a transgression result in [16] that show that it is sufficient to only use the degree-00 and degree-11 parts of the superconnection to construct currents that represent characteristic forms of cohesive modules in the Bott-Chern cohomology.
