A continuation principle for a class of periodically perturbed autonomous systems

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/138962In this paper we evaluate the topological index of periodic solutions otained via the Malkin-Loud bifurcation result. Incidentally, we do not assume that the perturbation is differentiale.Accepted to Math.
