Abstract

Let be a compact, irreducible Hermitian complex space of complex dimension  and with . Let be a Hermitian holomorphic vector bundle over , and let us denote by the rolled-up operator of the maximal --complex of -valued -forms. Let be a resolution of singularities, a metric on , and . In this paper, under quite general assumptions on , we prove the following equality of analytic -homology classes , with the rolled-up operator of the --complex of -valued -forms on . Our proof is based on functional analytic techniques developed in Kuwae and Shioya (2003) and provides an explicit homotopy between the even unbounded Fredholm modules induced by and .
