Using the Koszul duality theory of operads, we make the André-Quillen cohomology of algebras over an operad explicit. This cohomology theory is represented by a chain complex: the cotangent complex. We provide criteria for the André-Quillen cohomology theory to be an Ext-functor. In particular, this is the case for algebras over cofibrant operads and this gives a new stable homotopy property for these algebras. Then we generalize the Koszul duality theory of associative algebras in two independant directions. On the one hand, we extend the Koszul duality theory to non necessarily augmented operads in order to treat algebras with unit. The notion of curvature appears to encode the default of augmentation. As a corollary, we obtain homotopica...
