The monadic description of derived D-modules for derived affine schemes

About 1 year old · traced to

Let A∈\CAlg\C\cn,\lfpA \in \CAlg^{ \cn, \lfp }_{ \C } be possibly unbounded, let \g∈\LieAlgbdA\g \in \LieAlgbd_{ A }, and let \MC(\g)\MC(\g) be the formal moduli problem under \SpecA\Spec A associated to \g\g. The category \IndCoh0(\MC(\g)/A)\IndCoh_{ 0 }(\MC(\g)/A) is defined as in Beraldo's construction.

Derived D-module equivalence. There exists a symmetric monoidal equivalence

\IndCoh0(\MC(\g)/A)⟶∼\LModU(\g).\IndCoh_{ 0 }(\MC(\g)/A) \stackrel{\sim}{\longrightarrow} \LMod_{ U(\g) }.

This extends the known bounded case to possibly unbounded derived affine schemes. The claim concerns the compatibility between the ind-coherent definition of derived D-modules and representations of the universal enveloping algebra; the source says that the associated formal moduli problem should be used even though the relevant correspondence is not an equivalence.
