The 19-Vertex Model at critical regime $|q|=1$

Abstract

We study the 19-vertex model associated with the quantum group $U_q(\widehat{s{l}_2})$ at critical regime $|q|=1$. We give the realizations of the type-I vertex operators in terms of free bosons and free fermions. Using these free field realizations, we give the integral representations for the correlation functions.
