On deformations of Lie algebroids
Abstract
For any Lie algebroid A, its 1-jet bundle JA is a Lie algebroid naturally and there is a representation π: JA ->DA. Denote by dJ the corresponding coboundary operator. In this paper, we realize the deformation cohomology of a Lie algebroid A introduced by M. Crainic and I. Moerdijk as the cohomology of a subcomplex ((Hom(,A)DA), dJ) of the cochain complex ((Hom(,A)), dJ).
