Asymptotic Products and Enlargibility of Banach-Lie AlgebrasDaniel BeltitaDaniel BeltitaInstitute of Mathematics ``Simion Stoilow'' of the Romanian Academy P.O. Box 1-764 RO-70700 Bucharest Romania dbeltita@imar.ro Abstract: The paper provides a ``standard'' proof of a local theorem on enlargibility of Banach-Lie algebras. A particularly important special case of that theorem is that a Banach-Lie algebra is enlargible provided it has a dense locally finite subalgebra. The theorem is due to V. Pestov, who proved it by techniques of nonstandard analysis. The present proof uses a theorem concerning enlargibility of asymptotic products of contractive Banach-Lie algebras. Keywords: asymptotic product; enlargible Banach-Lie algebra Classification (MSC2000): 22E65; 17B65, 46B08 Full text of the article:
