Universal lifting theorem and quasi-Poisson groupoids

David Iglesias Ponte, Camille Laurent-Gengoux, Ping Xu

We prove the universal lifting theorem: for an $α$ -simply connected and $α$ -connected Lie groupoid $\gm$ with Lie algebroid $A$ , the graded Lie algebra of multi-differentials on $A…

Chern character for twisted K-theory of orbifolds

Jean-Louis Tu, Ping Xu

For an orbifold X and $α \in H^{3} (X, Z)$ , we introduce the twisted cohomology $H_{c}^{*} (X, α)$ and prove that the Connes-Chern character establishes an isomorphism between the twisted K…
