Title | Modular class of Poisson manifolds and Jacobi boundles |
Abstract |
In this talk, we will discuss modular classes of Poisson manifolds and Jacobi bundles. The study of modular classes of Poisson manifolds goes back to Koszul’s work in 1985. The modular class of a Poisson manifold is a class in the first Lichnerowicz-Poisson cohomology group that determines the obstruction to the existence of a volume form, which is invariant under the flows of all Hamiltonian vector fields. |
