Abstract:

A new kind of iteration technique for solving nonlinear ordinary differential equations is described and used to find approximate periodic solutions for some wellknown nonlinear problems. The most interesting features of the proposed method are its extreme simplicity and concise forms of iteration formula for a wide range of nonlinear problems.

Key words: iteration method, approximate periodic solution, ordinary differential equations
