Formality theorem with coefficients in a module
Abstract
In this article, will denote a manifold. In a very famous article, Kontsevich showed that the differential graded Lie algebra (DGLA) of polydifferential operators on is formal. Calaque extended this theorem to any Lie algebroid. More precisely, given any Lie algebroid over , he defined the DGLA of -polydifferential operators, , and showed that it is formal. Denote by the DGLA of -polyvector fields. Considering , a module over , we define the -module of -polyvector fields with values in . Similarly, we define the -module of -polydifferential operators with values in , . We show that there is a quasi-isomorphism of -modules over from to . Our result extends Calaque 's (and Kontsevich's) result.
