Quasi, twisted, and all that... in Poisson geometry and Lie algebroid theory
Quasi, twisted, and all that... in Poisson geometry and Lie algebroid theory
Motivated by questions from quantum group and field theories, we review structures on manifolds that are weaker versions of Poisson structures, and variants of the notion of Lie algebroid. We give a simple definition of the Courant algebroids and introduce the notion of a deriving operator for the Courant bracket …
