The Krylov-Bogoliuvob-Mitropolsky averaging method for polynomial dynamical systems
Abstract
We describe the transformation of a polynomial planar dynamical system into a second order differential equation by means of a polynomial change of variables. We then, by means of the Krylov-Bogoliubov-Mitropolsky averaging method, identify sufficient conditions involving said change of variables so that a limit cycle exists.
