摘要
We construct and investigate a short exact sequence of Poisson VB-groupoids which is canonically related to the Atiyah sequence of a G-principal bundle P. Our results include a description of the structure of the symplectic leaves of the Poisson groupoid T*P x T*P/G paired right arrows T*P/G. The semidirect product case, which is important for applications in Hamiltonian mechanics, is also discussed.
