Query: The 19-Vertex Model at critical regime $|q|=1$   We study the 19-vertex model associated with the quantum group
$U_q(\hat{sl_2})$ 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.
