Abstract
We give a necessary and sufficient condition for an ordering of a set of positive roots in a root system R to be associated to a reduced expression of a reduced expression of an element of the Weyl group of R. Finally we characterize the sets of positive roots which can be gives such and orderingFile allegati a questo prodotto
