Query: Exact Solution of an Electronic Model of Superconductivity in 1+1
  Dimensions   We study a superconducting integrable model of strongly correlated electrons
in 1+1 dimensions. We construct all six Bethe Ans\"atze for the model and give
explicit expressions for lowest conservation laws. We also prove a lowest
weight theorem for the Bethe-Ansatz states.
