Sousse, Tunisia mohamed.selmi@fss.rnu.tn Describing the Gelfand construction for the analytic states on an universal enveloping algebra, we characterize pure states and re-find the main result of a preceding work with L. Abdelmoula and J. Ludwig on the separation of unitary irreducible representations of a connected Lie group by their generalized moment sets. Keywords: Universal enveloping algebra, analytic states, moment set of a representation. MSC: 22D10, 22D20, 52A05 [ Fulltext-pdf (124 KB)] for subscribers only. |
