An approach to the tangential Poisson cohomology based on examples in duals of Lie algebras
Angela Gammella
We study the tangential Poisson cohomology (TP-cohomology) of regular Poisson manifolds, first defined by Lichnerowicz using contravariant tensor fields. We show that for a regular…

Tangential Star Products
Angela Gammella
We etablish a necessary and sufficient condition under which there exists a tangential and well graded star product, differential or not, on the dual g^* of a nilpotent Lie algebra…
