Superconnection and Orbifold Chern character

Qiaochu Ma, Xiang Tang, Hsian-Hua Tseng +1

We use flat antiholomorphic superconnections to study orbifold Chern character following the method introduced by Bismut, Shen, and Wei. We show the uniqueness of orbifold Chern ch…

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…
