Determinat formula for solutions of the $U_q(s{l}_n)$ qKZ equation at $|q|=1$

Abstract

We construct the hypergeometric solutions for the quantized KZ equation with values in a tensor product of vector representations of $U_q(s{l}_n)$ at $|q|=1$ and give an explicit formula for the corresponding determinant in terms of the double sine function.
