A Lie theoretic approach to the twisting procedure and Maurer-Cartan simplicial sets over arbitrary rings

Niek de Kleijn, Felix Wierstra

The Deligne-Getzler-Hinich--$\infty$-groupoid or Maurer-Cartan simplicial set of an $L_{\infty }$-algebra plays an important role in deformation theory and many other areas of mathema…
