Non-exactness of toric Poisson structures

Differential Geometry 2022-09-07 v1

Abstract

We prove that a Poisson structure on a projective toric variety which is invariant by the torus action and whose symplectic leaves are the torus orbits is not exact. This is deduced from a geometric criterion for non-exactness of Poisson structures with a finite number of symplectic leaves.
