T. Hasegawa et al., INTEGRAL SOLUTION OF TRIGONOMETRIC KNIZHNIK-ZAMOLODCHIKOV EQUATION - OFF-SHELL BETHE-ANSATZ METHOD, Journal of the Physical Society of Japan, 63(8), 1994, pp. 2895-2901
We construct the solutions of the su(2) trigonometric Knizhnik-Zamolod
chikov (KZ) equation based on the Babujian's ''off-shell Bethe ansatz'
' method. We show that the quasi-classical limit of the Bethe ansatz e
quation including the ''unwanted term'' for the inhomogeneous XXZ latt
ice reduces to the trigonometric KZ equation.
