Koszul Duality for Associative Algebras,the preceding method to handle the inhomogeneous quadratic case. Two examples are: the universal enveloping algebra . of a Lie algebra . (original example due to J.-L. Koszul) and the Steenrod algebra.

Bar and Cobar Construction of an Algebra over an Operad,otions of twisting morphism, bar and cobar constructions. When the operad . is Koszul, this allows us to define functorial quasi-free resolutions for .-algebras and .-algebras. They will be used in the next chapter to compute homology groups.

Pod and Seed Camouflage in the Genus ,ture is homotopy equivalent to the starting data. The operadic framework with the Koszul duality theory enables us to state explicitly this transfer of structure result..In this chapter, we give four equivalent definitions for the notion of homotopy .-algebra. We also introduce the notion of ∞-morphisms.
