We compute in this article the bracket structure on H1(m_0,m_0), H2(m_0,m_0) and in relation to this, we establish that there are only finitely many true deformations of m_0 in each nonpositive weight, by constructing them explicitely. It turns out that in weight 0 one gets exactly the other two filiform Lie algebras.", "revisions": [ { "version": "v2", "updated": "2007-08-30T20:54:00.000Z" } ], "analyses": { "subjects": [ "17B65", "58H15" ], "keywords": [ "infinite dimensional filiform lie algebra", "deformations", "infinite dimensional n-graded lie algebra", "cohomology" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007math......3383F" } } }
