Title: The Bar-Cobar construction for dg-algebras

Abstract:

The Bar and Cobar functors pair up to form an adjunction between the category of dg-algebras and dg-coalgebras. This adjunction can be used as a tool to provide a quasi-free resolution for any dg-algebra. We work out such a resolution for the case of a quadratic dg-algebra.
