Derived deformations of Artin stacks
Pages: 419 – 477
We generalise the techniques of derived deformations of schemes to describe derived deformations in simplicial categories. This allows us to consider deformation problems with higher automorphisms, such as chain complexes (which have homotopies) and stacks (which have 2-automorphisms).
