We compute explicitly the monodromy representations of “cyclotomic” analogs of the Knizhnik–Zamolodchikov differential system. These are representations of the type B braid group $${B_n^1}$$ . We show how the representations of the braid group Bn obtained using quantum groups and universal R-matrices may be enhanced to representations of $${B_n^1}$$ using dynamical twists. Then, we show how these “algebraic” representations may be identified with the above “analytic” monodromy representations.
