Speaker: Reyer Sjamaar, Cornell University

Abstract: We introduce the notion of a Hamiltonian action of an étale Lie group stack on an étale symplectic stack and establish versions of some basic theorems of symplectic geometry in this context, such as the Kirwan convexity theorem and the Mayer-Marsden-Weinstein symplectic reduction theorem. This is joint work with Benjamin Hoffman.
