Integrable system of generalized relativistic interacting tops

We describe a family of integrable models generalizing classical spin Ruijsenaars–Schneider systems (the case ) on one hand and relativistic integrable tops on the Lie group (the case ) on the other hand. We obtain the described models using the Lax pair with a spectral parameter and derive the equations of motion. To construct the Lax representation, we use the -matrix in the fundamental representation of .
