Composantes PRV généralisées et chemins de Littelmann
Résumé
We give a sufficient condition for a Littelmann's path to represent a vector of extremal weight of an integrable irreducible highest weight representation of a symmetrisable Kac-Moody algebra. Thanks to this condition, we present an alternative proof of recent result by Boris Pasquier, Nicolas Ressayre and the author of this article on the existence of generalized PRV components.
