摘要：

We show in two simple examples that for one-dimensional quantum chains with quantum group symmetries, the hamiltonian being nonhermitian in the massless regime, the correlation functions of local operators are, in general, infrared divergent. If one considers, however, correlation functions invariant under the quantum group, the divergences cancel out.
