We introduce a new object--``Weinstein groupoid'', which is a differentiable stack with groupoid-like axioms. With it, we have solved the integration problem of Lie algebroids. It turns out that every Weinstein groupoid has a Lie algebroid and every Lie algebroid can be integrated into a Weinstein groupoid.", "revisions": [ { "version": "v5", "updated": "2006-11-27T18:21:51.000Z" } ], "analyses": { "keywords": [ "integrating lie algebroids", "weinstein groupoid", "lie groupoids", "integration problem" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......5003T" } } }
