Stacky Hamiltonian actions and symplectic reduction

Benjamin Hoffman, Reyer Sjamaar, Chenchang Zhu

We introduce the notion of a Hamiltonian action of an étale Lie group stack on an étale symplectic stack and establish versions of the Kirwan convexity theorem, the Meyer-Marsden-W…

Cohomological localization for transverse Lie algebra actions on Riemannian foliations

Yi Lin, Reyer Sjamaar

We prove localization and integration formulas for the equivariant basic cohomology of Riemannian foliations. As a corollary we obtain a Duistermaat-Heckman theorem for transversel…
