FUSION RULES FOR THE q-VERTEX OPERATORS OF ${\rm U}_q (\widehat{{\rm sl} (2)})$
We analyze the properties of the q-vertex operators [Formula: see text] introduced by Frenkel and Reshetikhin. As the condition for the null vector decoupling, we derive the existence condition of the q-vertex operators (the fusion rules).
