DG-modules over de Rham DG-algebra
Abstract
For a morphism of smooth schemes over a regular affine base we define functors of derived direct image and extraordinary inverse image on coderived categories of DG-modules over de Rham DG-algebras. Positselski proved that for a smooth algebraic variety $X$ over a field $k$ of characteristic zero the coderived category of DG-modules over $Ω^\bullet_{X/k}$ is equivalent to the unbounded derived category of quasi-coherent right ${\mathscr D}_X$-modules. We prove that our functors correspond to the functors of the same name for ${\mathscr D}_X$-modules under Positselski equivalence.
