Summary: We study radially symmetric systems with a repulsive singularity, and show the existence of periodic orbits with small angular momentum. Our proofs are based on the use of topological degree theory.
Classification : 34C25
Keywords: periodic solutions, singular radially symmetric systems, topological degree theory
