A residue current associated with a twisting cochain: duality and comparison formula

Complex Variables 2023-06-06 v1

Abstract

Let F\mathcal{F}^\bullet be a complex of coherent OX\mathcal{O}_X-modules over a complex manifold XX. We give a construction of a residue current associated with this complex that generalizes Andersson and Wulcan's construction of a residue current associated with a coherent OX\mathcal{O}_X-module F\mathcal{F}. The main ingredients are to give a construction of a residue current associated with a twisting cochain in the sense of Toledo and Tong and to establish a comparison formula for these currents that generalizes an analogous formula given by L\"ark\"ang.
