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…

Twisted K-theory of differentiable stacks

Jean-Louis Tu, Ping Xu, Camille Laurent-Gengoux

In this paper, we develop twisted $K$ -theory for stacks, where the twisted class is given by an $S^{1}$ -gerbe over the stack. General properties, including the Mayer-Vietoris propert…
