FREE RESOLUTIONS FOR DIFFERENTIAL MODULES OVER DIFFERENTIAL ALGEBRAS

摘要

A free resolution (R,d + h) → (M,d) for a DG-module (M,d) over a DG-algebra (A,d) is constructed in the sense of a perturbation of the differential in a free bigraded resolution (R,d) → M of the underlying graded module M over an underlying graded algebra A.
