Limit cycles from a monodromic infinity in planar piecewise linear systems
Emilio Freire, Enrique Ponce, Joan Torregrosa +1
Planar piecewise linear systems with two linearity zones separated by a straight line and with a periodic orbit at infinity are considered. By using some changes of variables and p…
Bifurcation set for a disregarded Bogdanov-Takens unfolding. Application to 3D cubic memristor oscillators
Andrés Amador, Emilio Freire, Enrique Ponce
We derive the bifurcation set for a not previously considered three-parametric Bogdanov-Takens unfolding, showing that it is possible express its vector field as two different pert…
Canards, folded nodes and mixed-mode oscillations in piecewise-linear slow-fast systems
Mathieu Desroches, Antoni Guillamon, Enrique Ponce +3
Canard-induced phenomena have been extensively studied in the last three decades, both from the mathematical and from the application viewpoints. Canards in slow-fast systems with…
A simple solution to the Braga-Mello conjecture
Douglas Duarte Novaes, Enrique Ponce
Recently Braga and Mello conjectured that for a given natural number n there is a piecewise linear system with two zones in the plane with exactly n limit cycles. In this paper we…
