Twisted cohomology of Lie algebroids

Abstract

In this short note we define a new cohomology for a Lie algebroid A\mathcal{A}, that we call the \emph{twisted cohomology} of A\mathcal{A} by an odd cocycle θ\theta in the Lie algebroid cohomology of A\mathcal{A}. We proof that this cohomology only depends on the Lie algebroid cohomology class [θ][\theta] of the odd cocycle θ\theta. We give a few examples showing that this new cohomology encompasses various well-known cohomology theories.
