Abstract The XXZ spin-chain Hamiltonian has been constructed to be su(2) q -invariant, but naively does not appear to be su(2)-invariant. However, using recently discovered deforming maps between representations of su(2) q and corresponding representations of su(2), we prove a theorem which states that if a Hamiltonian is su(2) q -invariant, it is also su(2)-invariant. The theorem generalizes to any quantized Lie algebra.
