Derived Geometric Methods in Supergeometry: Transmutations and their Cohomology

Abstract

We study the stacky approach to cohomology in the super setting. We introduce the classic transmutation stacks (Betti, de Rham and Dolbeault) due to Simpson, which are geometric realizations of locally constant sheaves, D-modules and Higgs bundles respectively and we give new proofs for results due to Penkov on $D$-Modules and the isomorphism between de Rham cohomology and super de Rham cohomology. To do this, we will develop the theory of derived categories on superstacks establishing, amongst others, base change and recollement theorems. The goal of this paper is to demonstrate the usage of ideas and methods coming from derived algebraic geometry in the supergeometric setting as derived and super have geometric similarities, which lead to the same considerations when adapting classical notions to their respective settings.
