This article summarizes the results of two recent investigations with A. Doikou on symmetries of integrable quantum spin chains which have been motivated in part by the computation of exact boundary and bulk scattering matrices.

We discuss some fundamental properties of the XXZ spin chain, which are important in the algebraic Bethe-ansatz derivation for the multiple-integral representations of the spin-s XXZ correlation function with an arbitrary product of elementary matrices. For instance, we construct Hermitian conjugate vectors in the massless regime and introduce the spin-s Hermitian elementary matrices.
