The homotopy analysis method and the Lienard equation 2011 In this article, Liénard equations are considered. The limit cycles of these systems are studied by applying the homotopy analysis method (HAM). The amplitude and frequency obtained with this methodology are in good agreement with those calculated by computational methods. This puts in evidence that HAM is a useful tool to solve nonlinear differential equations.
