Integrating Poisson manifolds via stacks

Hsian-Hua Tseng, Chenchang Zhu

A symplectic groupoid $G . := (G_{1} ⇉ G_{0})$ determines a Poisson structure on $G_{0}$ . In this case, we call $G .$ a symplectic groupoid of the Poisson manifold $G_{0}$ . How…

Integrating Lie algebroids via stacks

Hsian-Hua Tseng, Chenchang Zhu

Lie algebroids can not always be integrated into Lie groupoids. We introduce a new object--``Weinstein groupoid'', which is a differentiable stack with groupoid-like axioms. With i…
