As an example, we show how hamiltonian quasi-Poisson manifolds fit into this framework by constructing an ``inversion'' procedure relating quasi-Poisson bivectors to twisted Dirac structures.", "revisions": [ { "version": "v3", "updated": "2004-10-19T17:28:37.000Z" } ], "analyses": { "keywords": [ "moment maps", "hamiltonian quasi-poisson manifolds fit", "procedure relating quasi-poisson bivectors", "symplectic groupoids", "momentum maps" ], "note": { "typesetting": "TeX", "pages": 36, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003math.....10445B" } } }
