Toric symplectic stacks (Benjamin Hoffman, Cornell)

13.02.2019 10:30

We give an intrinsic definition of toric symplectic stacks, and show that they are classified by simple convex polytopes equipped with some additional combinatorial data. This is a generalization of Delzant's theorem classifying toric symplectic manifolds. As an application, we show that any toric symplectic stack can be deformed to an ineffective toric orbifold.
