Characters of fundamental representations of quantum affine algebras

By Vyjayanthi Chari, Adriano and A. Moura

Abstract

Abstract. We give closed formulae for the q–characters of the fundamental representations of the quantum loop algebra in terms of a family of partitions satisfying some simple properties. We also give the multiplicities of the eigenvalues of the imaginary subalgebra in terms of these partitions
