Un schéma simplicial de Grothendieck-Pridham

Pridham has shown that any Artin $n$-stack $M$ has a presentation as a simplicial scheme $X$ satisfying certain smoothness properties originally introduced by Grothendieck. In the previous paper we introduced an Artin $n$-stack $M$ of Maurer-Cartan elements of a dg-category and constructed a chart, and have already proven the first conditions of smoothness of $X_1\rightarrow X_0$ explicitly. In this paper, we will construct explicitly the full simplicial scheme and show the Grothendieck-Pridham smoothness conditions, implying that $M$ is a geometric $n$-stack.

Géométricité artinienne de l'$\infty$-champs des éléments de Maurer-Cartan

In this paper, based on the same techniques as in \cite{BENZ08} for the construction of a formally smooth map $V \to Perf$ from the variety of complexes to the Artin $\infty$-stack $Perf$, we explicitly construct a new Artin $ \infty $-stack of Maurer-Cartan elements of a dg-category $ \mathcal {P} $ denoted by $\mathcal{MC_P} $, with a map $ V \to \mathcal{MC_P} $ which we show to be formally smooth.
