Abstract

A procedure is described that makes use of the generating function of characters to obtain a new generating function HH giving the multiplicities of each weight in all the representations of a simple Lie algebra. The way to extract from HH explicit multiplicity formulas for particular weights is explained and the results corresponding to rank two simple Lie algebras shown.
