Comments on "New representations of the Hecke algebra and algebraic Bethe Ansatz for an integrable generalized spin ladder", by H.-Q. Zhou, H. Frahm and M.D. Gould, cond-mat/9911072

Abstract

The authors of cond-mat/9911072 claim to introduce "new representations of the Hecke algebra." These representations are shown to be the XXC models introduced two years ago in solv-int/9712008, and repeatedly studied and referred to in subsequent papers. They are in fact representations of the Temperley-Lieb algebra. Several other remarks are made and mistakes are pointed out.
