Hochschild cohomology of Lie-Rinehart algebras
Bjarne Kosmeijer, Hessel Posthuma
We compute the Hochschild cohomology of universal enveloping algebras of Lie-Rinehart algebras in terms of the Poisson cohomology of the associated graded quotient algebras. Centra…

A note on the equivariant Chern character in Noncommutative Geometry
Bjarne Kosmeijer, Hessel Posthuma
Given a smooth action of a Lie group on a manifold, we give two constructions of the Chern character of an equivariant vector bundle in the cyclic cohomology of the crossed product…

Quantization of Whitney functions
M. J. Pflaum, H. Posthuma, X. Tang
We propose to study deformation quantizations of Whitney functions. To this end, we extend the notion of a deformation quantization to algebras of Whitney functions over a singular…
