We compute the ordinary cohomology groups $H^q({\\frak m}_0^\\lambda(p))$ and restricted cohomology groups $H^q_*({\\frak m}_0^\\lambda(p))$ for $q=1, 2$, and we give explicit descriptions of bases for these cohomology spaces. We apply our results to restricted one-dimensional central Extensions of the algebras ${\\frak m}_0^\\lambda(p)$.", "revisions": [ { "version": "v1", "updated": "2018-01-24T20:41:45.000Z" } ], "analyses": { "subjects": [ "17B56", "15B50" ], "keywords": [ "restricted one-dimensional central extensions", "restricted filiform lie algebras", "truncated filiform lie algebra", "restricted lie algebra structures", "ordinary cohomology groups" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable" } } }
