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…

The modular class of a twisted Poisson structure

Yvette Kosmann-Schwarzbach, Camille Laurent-Gengoux

We study the geometric and algebraic properties of the twisted Poisson structures on Lie algebroids, leading to a definition of their modular class and to an explicit determination…

Godbillon-Vey classes for super-foliations

Camille Laurent-Gengoux

We construct the equivalent of the Godbillon-Vey class and its generalizations for regular foliations on super-manifolds. We interpret these classes as classes of foliated flat con…

Chern-Weil map for principal bundles over groupoids

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

The theory of principal -bundles over a Lie groupoid is an important one, unifying the various types of principal -bundles, including those over manifolds, those over orbifol…

Quantization of Quasi-Presymplectic Groupoids and their Hamiltonian Spaces

Camille Laurent-Gengoux, Ping Xu

We study the prequantization of quasi-presymplectic groupoids and their Hamiltonian spaces using -gerbes. We give a geometric description of the integrality condition. As an a…

Twisted K-theory of differentiable stacks

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

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