On the Cohomology of the spaces of differential operators acting on skewsymmetric tensor fields or on forms, as modules of the Lie algebra of vector fields
B. Agrebaoui, F. Ammar, P. Lecomte
The space of differential operators acting on skewsymmetric tensor fields or on smooth forms of a smooth manifold are representations of its Lie algebra of vector fields. We comput…

Multi-parameter deformations of the module of symbols of differential operators
F. Ammar, B. Agrebaoui, V. Ovsienko
The space of symbols of differential operators on a smooth manifold (i.e., the space of symmetric contravariant tensor fields) is naturally a module over the Lie algebra of vector…
