The Birkhoffian, the Birkhoff's functions, the Pfaff action, the Pfaff-Birkhoff principle and the Birkhoff equations of relativistic Birkhoff systems are given. The Birkhoff representation of relativistic dynamical systems is studied. Then the theory of Noether symmetries and Lie symmetries of the relativistic Birkhoff systems is obtained by the in...

The basic integration theory of the dynamics of a rotational relativistic system is constructed. Firstly, the first integrals of the system are given. Secondly, the order of the equation of motion is reduced by using cyclic integrals and energy integrals, and thus the generalized Routh equation and generalized Whittaker equation are obtained.
