摘要：

We show the connection between the extended centre of the quantum group in roots of unity and the restriction of the XXZ model. We also give explicit expressions for operators that respect the restriction and act on the state space of the restricted models. The formulae for these operators are verified by explicit calculation for third-degree roots; they are conjectured to hold in the general case.
