Nondynamical r -Matrix Structure of the sl 2 Trigonometric Ruijsenaars-Schneider Model
Kai Chen, Bo-Yu Hou, Wen‐Li Yang +1 more
It is shown that the sl 2 trigonometric Ruijsenaars-Schneider model admits a nondynamical r -matrix structure under a certain gauge. The corresponding r -matrix is the classical limit of a twisted trigonometric R -matrix. The new factorized classical and quantum L -operators are obtained.
