چکیده

In honor of the 100th birthday of the article, " Sur les groupes continus " Abstract: A methodical analysis of the research related to the article , " Sur les groupes continus " , of Henri Poincaré reveals many historical misconceptions and inaccuracies regarding his contribution to Lie theory. A thorough reading of this article confirms the precedence of his discovery of many important concepts, especially that of the universal enveloping algebra of a Lie algebra over the real or complex field, and the canonical map (symmetrization) of the symmetric algebra onto the universal enveloping algebra. The essential part of this article consists of a detailed discussion of his rigorous, complete, and enlightening proof of the so-called Birkhoff-Witt theorem. TITRE: La démonstration de Poincaré du théorème de Birkhoff-Witt. R ´ ESUMÉ: Une analyse méthodique des travaux faits en connexion avec l'article, " Sur les groupes continus " , de Henri Poincaré révèle des erreurs historiques et des jugements injustes en ce qui concerne sa contributionà la théorie de Lie. Uné etude approfondie de cet article confirme la précédence de sa découverte de plusieurs concepts importants; notamment de l'algèbre enveloppante universelle d'une algèbre de Lie sur le corps réel ou le corps complexe, et de l'application canonique (la symétrisation) de l'algèbre symétrique sur l'algèbre enveloppante universelle. L'essentiel de cet article consiste en un examen approfondi de sa démonstration rigoureuse etcompì ete du théorème de Birkhoff-Witt. Liste de quelques mots-clés: L'algèbre enveloppante universelle, l'application canonique (symétrisation), le théorème de Birkhoff-Witt.

A Poincaré-birkhoff-witt Theorem for Generalized Lie Color Algebras

A proof of Poincaré-Birkhoff-Witt theorem is given for a class of generalized Lie algebras closely related to the Gurevich S-Lie algebras. As concrete examples, we construct the positive (negative) parts of the quantized universal enveloping algebras of type An and Mp,q,ǫ(n, K), which is a nonstandard quantum deformation of GL(n). In particular, we get, for both algebras, a unified proof of the...

THE POSITIVE PART OF THE QUANTIZED UNIVERSAL ENVELOPING ALGEBRA OF TYPE AnAS A BRAIDED QUANTUM GROUP

The aim of this paper is to explain the bialgebra structure of the positive part of the quantized universal enveloping algebra (Drinfeld-Jimbo quantum group) of type Anusing the Lie algebra theory concepts. Recently has been introduced a generalization of Lie algebras, the basic T -Lie algebras [1]. Using the T -Lie algebra concept some new (we think) quantum groups of type Ancan be constructed...

and triples of operads

We introduce the notion of generalized bialgebra, which includes the classical notion of bialgebra (Hopf algebra) and many others. We prove that, under some mild conditions, a connected generalized bialgebra is completely determined by its primitive part. This structure theorem extends the classical Poincaré-Birkhoff-Witt theorem and the Cartier-Milnor-Moore theorem, valid for cocommutative bia...

Constructing homomorphisms between Verma modules

We describe a practical method for constructing a nontrivial homomorphism between two Verma modules of an arbitrary semisimple Lie algebra. With some additions the method generalises to the affine case. A theorem of Verma, Bernstein-Gel’fand-Gel’fand gives a straightforward criterion for the existence of a nontrivial homomorphism between Verma modules. Moreover, the theorem states that such hom...
