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.

Use of theory of Lie algebroids in (better) understanding of generalised complex structures
Let $M$ be a smooth manifold. A Lie algebroid over $M$ is a vector bundle $E\rightarrow M$ over $M$, with a Lie bracket on $\Gamma(M,E)$, a morphism of vector bundles $\rho:E\rightarrow TM$, such that …

Is there a notion of representation theory of foliations?
A foliation on a manifold $M$ can be seen as a sub bundle of the tangent bundle $\mathcal{F}\subseteq TM$ that is closed under Lie bracket of vector fields.
One can think of foliation as a Lie algebro …

First examples of Lie-Rinehart algebras that are not coming from Lie algebroids
I heard the idea of a Lie-Rinehart algebra first time from an algebraist.
I noticed there is a similarity between description of Lie algebroid on a manifold and the algebraic notion of Lie-Rinehart al …

Relation between equivariant geometry and representation theory (of geometric objects)
Equivariant geometry studies "manifolds" with an extra structure $G\times M\rightarrow M$.
Representation theory studies "Lie algebroids" with an extra structure $\Gamma(M,A)\times \Gamma(M,E)\rightar …
