Non Abelian Differentiable Gerbes
Camille Laurent-Gengoux, Mathieu Stienon, Ping Xu
We study non-abelian differentiable gerbes over stacks using the theory of Lie groupoids. More precisely, we develop the theory of connections on Lie groupoid -extensions, which…
Reduction of Generalized Complex Structures
Mathieu Stienon, Ping Xu
We study reduction of generalized complex structures. More precisely, we investigate the following question. Let be a generalized complex structure on a manifold , which adm…
Universal lifting theorem and quasi-Poisson groupoids
David Iglesias Ponte, Camille Laurent-Gengoux, Ping Xu
We prove the universal lifting theorem: for an -simply connected and -connected Lie groupoid $\gm$ with Lie algebroid , the graded Lie algebra of multi-differentials on $A…
A Class of integrable Spin Calogero-Moser systems II: Exact Solvability
Luen-Chau Li
In a previous paper, we introduce a class of integrable spin Calogero-Moser systems associated with the classical dynamical r-matrices with spectral parameter. Here the main purpos…
Chern character for twisted K-theory of orbifolds
Jean-Louis Tu, Ping Xu
For an orbifold X and , we introduce the twisted cohomology and prove that the Connes-Chern character establishes an isomorphism between the twisted K…
