    For the Lie algebra glNgl_N we introduce a system of differential operators called the dynamical operators. We prove that the dynamical differential operators commute with the glNgl_N rational quantized Knizhnik-Zamolodchikov difference operators. We describe the transformations of the dynamical operators under the natural action of the glNgl_N Weyl group.Comment: 7 pages, AmsLaTe
