Abstract
We consider the q -deformed Knizhnik-Zamolodchikov equation for the two point function of q -deformed vertex operators of Uq (\widehat sl2 ). We give explicitly the fundamental solutions, the connection matrices and the exchange relations for the q -vertex operators of spin 1/2 and j ∈ (1/2) Z≥0 . Consequently, we confirm that the connection matrices are equivalent to the elliptic Boltzmann weights of IRF type obtained by the fusion procedure from ABF models.
