Examples of Sullivan models in rational homotopy theory:
The equivariant version of rational homotopy theory.
equivariant chain complex, model structure on equivariant chain complexes
Quillen adjunction between equivariant simplicial sets and equivariant connective dgc-algebras
fundamental theorem of dg-algebraic equivariant rational homotopy theory
