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…

Dirac submanifolds and Poisson involutions
Ping Xu
Dirac submanifolds are a natural generalization in the Poisson category for symplectic submanifolds of a symplectic manifold. In a certain sense they correspond to symplectic subgr…
