Drinfeld-Kohno theorem

**Drinfelâ€™d-Kohno theorem** is about a geometric relation between classical and quantum $R$-matrices for quantum groups: the monodromies of the solutions of Knizhnik-Zamolodchikov equations (which are equations of Fuchsian type) for a given classical $r$-matrix give rise to the corresponding quantum $R$-matrix; more precisely it gives the same representation of the braid group.
