Query: Classification of the solutions of constant rational semi-dynamical
  reflection equations   We propose a classification of the solutions K to the semi-dynamical
reflection equation with constant rational structure matrices associated to
rational scalar Ruijsenaars-Schneider model. Four sets of solutions are
identified and simple analytic transformations generate all solutions from
these sets.
