| Abstract: | This paper deals with the numerical periodic solutions of nonlinear dynamical systems. The fold point singularity of the homotopy of periodic solutions is discussed, and the sufficient and necessary condition for the fold point is also given. Then a novel monotone homotopy method is developed for solving the periodic solution and its global convergence is proved as well. Finally the effectiveness of this method is illustrated with a numerical example. |
