Abstract

If AA is a Lie algebroid over a foliated manifold (M,F)(M,\mathcal{F}), a foliation of AA is a Lie subalgebroid BB with anchor image TFT\mathcal{F} and such that A/BA/B is locally equivalent with Lie algebroids over the slice manifolds of F\mathcal{F}. We give several examples and, for foliated Lie algebroids, we discuss the following subjects: the dual Poisson structure and Vaintrob's super-vector field, cohomology and deformations of the foliation, integration to a Lie groupoid. In the last section, we define a corresponding notion of a foliation of a Courant algebroid AA as a bracket-closed, isotropic subbundle BB with anchor image TFT\mathcal{F} and such that B/BB^\perp/B is locally equivalent with Courant algebroids over the slice manifolds of F\mathcal{F}. Examples that motivate the definition are given.
