A Renormalization Method to Asymptotically Solve Weakly Nonlinear Systems of ODEs for Long Times

Regularly perturbed systems of ODEs have been traditionally solved using two-timing or averaging methods. The new renormalization technique, based on preliminary efforts of theoretical physicists, often allows asymptotic solutions to be constructed on very long time intervals.
