This generalizes Kostant theorem to the integral cohomology of the positive system.", "revisions": [ { "version": "v1", "updated": "2013-08-08T00:54:32.000Z" } ], "analyses": { "keywords": [ "integral cohomology", "generalization", "generalizes kostant theorem", "semi-simple lie algebra", "positive system" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1308.1724Z" } } }
