| Abstract: | This work gives a discrimination method of the existence uniqueness and stability of the periodicsolutions for a nonlinear dynamical system with many degrees of freedom by appling the idea of the perturbation method and the techniques of the subspace.The present method summarizes the questionsinto the computations of the primary integrals.The main characterisitics of this approach are simple incalculations and convenient in applications.Two examples are given,finally. |
