Multiple solutions for periodic perturbations of a delayed autonomous system near an equilibrium
Pablo Amster, Mariel P. Kuna, Gonzalo Robledo
Small non-autonomous perturbations around an equilibrium of a nonlinear delayed system are studied. Under appropriate assumptions, it is shown that the number of -periodic solut…
