Stability of singular points of Poisson manifolds

Abstract: Roughly speaking, an order k singular point for a smooth Poisson structure is stable if all nearby Poisson structures have nearby singular points of order k. In this talk, we will give sufficient conditions for stability lying on the k-jet of the given Poisson structure at a singular point of order k. We will present several examples of stable singular points for Poisson structures.
