Poisson geometry around Poisson submanifolds

Abstract

We construct a first-order local model for Poisson manifolds around a large class of Poisson submanifolds and give conditions under which this model is a local normal form. The resulting linearization theorem includes as special cases all the known linearization theorems for fixed points and symplectic leaves. The symplectic groupoid version of these results gives a solution to the groupoid coisotropic embedding problem.
