Equivariant Cohomology and Localization for Lie Algebroids

Let $M$ be a manifold carrying the action of a Lie group $G$, and let $A$ be a Lie algebroid on $M$ equipped with a compatible infinitesimal $G$-action. Using these data, we construct an equivariant cohomology of $A$ and prove a related localization formula for the case of compact $G$. By way of application, we prove an analog of the Bott formula.
