[Formule homotopique de Cartan et le complexe de Hochschild bivariant]
Comptes Rendus. Mathématique, Volume 347 (2009) no. 17-18, pp. 997-1000.

La formule LD=[eD+ED,b¯+B¯] (voir Goodwillie [Cyclic homology, derivations, and the free loopspace, Topology 24 (2) (1985) 187–215]) sur le complexe de Hochschild normalisé joue le rôle, en géométrie non commutative, de la formule homotopique de Cartan en homologie de Rham. Notre but est détendre cette formule au complexe de Hochschild bivariant normalisée.

The formula LD=[eD+ED,b¯+B¯] (see Goodwillie [Cyclic homology, derivations, and the free loopspace, Topology 24 (2) (1985) 187–215]) on the normalized Hochschild complex is the standard replacement in noncommutative geometry for the classical Cartan homotopy formula. Our purpose is to extend this formula to the normalized bivariant Hochschild complex.
