In differential geometry, Lie algebroids generalize on one hand Lie algebras, on the other hand the tangent bundle of a manifold: they are vector bundles equipped with an anchor map, i.e. a vector bundle morphism to the tangent bundle, and a Lie algebra structure on the space of sections subject to certain Leibniz rules. The integrated version of a Lie algebroid is a Lie groupoid. A purely algebraic version is a Lie-Rinehart algebra.

First examples of Lie-Rinehart algebras that are not coming from Lie algebroids

Yes, there are many such Lie-Rinehart algebras. To understand such examples we need to recall some classical geometric results. Note that a $C^\infty(M)$- module is the space of global sections of a s …
