Rigidity and Flexibility in Poisson Geometry

Rui Loja Fernandes, Marius Crainic

We discuss several rigidity and flexibility phenomena in the context of Poisson geometry.

Generalized complex structures and Lie brackets

Marius Crainic

We look at generalized complex structures from the point of view of Poisson and Dirac geometry and we remark that the puzzling equations underlying the notion of generalized comple…

Prequantization and Lie brackets

Marius Crainic

We start by describing the relationship between the classical prequantization condition and the integrability of a certain Lie algebroid associated to the problem and use this to g…

On the perturbation lemma, and deformations

M. Crainic

We have one more look at the (homological) perturbation lemma and we point out some non-standard consequences, including the relevance to deformations.

Deformations of Lie brackets: cohomological aspects

M. Crainic, I. Moerdijk

We introduce a new cohomology for Lie algebroids, and prove that it provides a differential graded Lie algebra which ``controls'' deformations of the structure bracket of the algeb…

Integrability of Poisson brackets

Marius Crainic, Rui Loja Fernandes

We show that various notions of integrability for Poisson brackets are all equivalent, and we give the precise obstructions to integrating Poisson manifolds. We describe the integr…
