The basic integration theory of the dynamics of a rotational relativistic s
ystem is constructed. Firstly, the first integrals of the system are given.
Secondly, the order of the equation of motion is reduced by using cyclic i
ntegrals and energy integrals, and thus the generalized Routh equation and
generalized Whittaker equation are obtained. Thirdly, the canonical equatio
n and variational equation of the system are established, and the integral
invariant is constructed by using the first integrals. Fourthly, the integr
al variants and integral invariants of the Poincare-Cartan type are given.
Finally, some deductions are given.
