MPIM Lecture Hall To a Poisson manifold $(M,\pi)$ one can naturally associated a cohomology called Poisson cohomology. Although Poisson cohomology is important for questions such as linearization and deformations of poisson structures, it is in general quite difficult to compute. In this talk we look at the Poisson structure on the dual of a Lie algebra $(g, [~,~])$. We look at the relation of Poisson cohomology with the linearization problem and outline the general ideas behind the calculations for the case of $\mathrm{sl}_2(\mathbb{C})$. This is based on joint work with Ioan Marcut.
