Enveloping algebras of infinite-dimensional Lie algebras
10 avril 2026 - 16:00Salle de conférences IRMA
Résumé : (Universal) enveloping algebras of finite-dimensional Lie algebras are among the most well-understood noncommutative rings: in fact, many of the fundamental techniques of ring theory were developed in order to understand these enveloping algebras. However, when the Lie algebra becomes infinite-dimensional, its enveloping algebras becomes much more mysterious. This talk will survey what's known about enveloping algebras of infinite-dimensional Lie algebras, starting with the definition and focussing on noetherianity questions and applications to representation theory. -
