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.

When does a VBLA induce an isomorphism on Lie algebroid cohomology?

The short answer is that a VBLA always induces an injection on cohomology, but in general it isn't an isomorphism. The less short answer is that the complex for $D \to B$ decomposes as a direct sum …
