Periodic orbits with small angular momentum for singular radially symmetric systems (English)
0 references
The author studies radially symmetric systems of second order ordinary differential equations with a repulsive singularity, and shows the existence of periodic orbits with small angular momentum. The proofs, inspired from previous work of the reviewer and R. Toader, are based on the use of topological degree theory.
