Abstract

In this article, XX will denote a C{\cal C}^{\infty} manifold. In a very famous article, Kontsevich showed that the differential graded Lie algebra (DGLA) of polydifferential operators on XX is formal. Calaque extended this theorem to any Lie algebroid. More precisely, given any Lie algebroid EE over XX, he defined the DGLA of EE-polydifferential operators, Γ(X,EDpoly)\Gamma (X, ^{E}D^{*}_{poly}), and showed that it is formal. Denote by Γ(X,ETpoly)\Gamma (X, ^{E}T^{*}_{poly}) the DGLA of EE-polyvector fields. Considering MM, a module over EE, we define Γ(X,ETpoly(M))\Gamma (X, ^{E}T_{poly}^{*}(M)) the Γ(X,ETpoly)\Gamma (X, ^{E}T^{*}_{poly})-module of EE-polyvector fields with values in MM. Similarly, we define the Γ(X,EDpoly)\Gamma (X, ^{E}D^{*}_{poly})-module of EE-polydifferential operators with values in MM, Γ(X,EDpoly(M))\Gamma (X, ^{E}D^{*}_{poly}(M)). We show that there is a quasi-isomorphism of LL_{\infty}-modules over Γ(X,ETpoly)\Gamma (X, ^{E}T^{*}_{poly}) from Γ(X,ETpoly(M))\Gamma (X, ^{E}T^{*}_{poly}(M)) to Γ(X,EDpoly(M))\Gamma (X, ^{E}D^{*}_{poly}(M)). Our result extends Calaque 's (and Kontsevich's) result.
