Comment on the paper ``Bound States in the One-dimensional Hubbard Model''
Abstract
We comment on the preprint cond-mat/9805103 by D. Braak and N. Andrei BrAn98. We point out that the ``new'' Bethe Ansatz equations presented in BrAn98 are identical to the Bethe equations for strings introduced by M. Takahashi for the description of thermodynamics in 1972 Takahashi72. Some physics suggested in BrAn98 is incorrect. In particular, all former conclusions made on the basis of the string Bethe equations remain valid.
