Using this, we give a sufficient condition for a tensor product of finite-dimensional representations of quantum affine algebras to be cyclic on the tensor product of highest weight vectors. In particular, this proves a generalization of a recently established conjecture of Akasaka and Kashiwara (see qa/0010293 and qa/0006084).Quantum AlgebraRepresentation Theory17B37 81R50text
