摘要：

We consider a large class of quantum spin chains, whose Hamiltonians commute with generators of a quantum algebra and which are integrable. We argue that the corresponding transfer matrices also commute with the quantum algebra. For the spin s A1(1) chain, we show that the Bethe states are highest weight states of U(q)[su(2)].
