Periodic solutions of a class of singular radially symmetric perturbations systems

Wenya Xing, Qing Zhang

Abstract


In this paper, we study the existence of infinitely many periodic solutions to planar radially symmetric systems with repulsive singular forces. The proof of the main result relies on topological degree theory and the global continuation principle of Leray-Schauder, together with a truncation technique. Recent result in the literature are generalized and significantly improved.
