Periodic solutions for Lienard differential equations with singularities
In this article, we study the second-order forced Lienard equation x''+f(x)x'+g(x)=e(t). By using the topological degree theory, we prove that the equation has at least one positive periodic solution when g admits a repulsive singularity near the origin and satisfies some semiline...
