They are a consistent system of difference equations satisfied by the N-point functions, the vacuum expectations of products of primary fields.
In the limit as the deformation parameter q approaches 1, the N-point functions of the quantum affine algebra tend to those of the affine Kac–Moody algebra and the difference equations become partial differential equations.
The quantum KZ equations have been used to study exactly solved models in quantum statistical mechanics.
