High Quality Content by WIKIPEDIA articles! In mathematical physics, the quantum KZ equations or quantum Knizhnik–Zamolodchikov equations or qKZ equations are the analogue for quantum affine algebras of the Knizhnik–Zamolodchikov equations for affine Kac–Moody algebras. 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. In other words, the classical limit of the quantum KZ equations yield the trigonometric form of the classical KZ equations. That is, in the limit as q approaches 1, the quantum affine algebra Uq(g) tends to the universal enveloping algebra U(g) and the correlation functions for the quantum case converges to the classical correlation functions.
