A new simple proof for Lum–Chua's conjecture
Carmona Centeno, Victoriano; Fernández Sánchez, Fernando; Novaes, Douglas D. (Elsevier, 2021-05)The already proved Lum–Chua’s conjecture says that a continuous planar piecewise linear differential system with two zones ...

A Succinct Characterization of Period Annuli in Planar Piecewise Linear Differential Systems with a Straight Line of Nonsmoothness
Carmona Centeno, Victoriano; Fernández Sánchez, Fernando; Novaes, Douglas D. (Springer, 2023-07)We close the problem of the existence of crossing period annuli in planar piecewise linear differential systems with a ...

Existence of a Reversible T-Point Heteroclinic Cycle in a Piecewise Linear Version of the Michelson System
Carmona Centeno, Victoriano; Fernández Sánchez, Fernando; Teruel Aguilar, Antonio Esteban (Society for Industrial and Applied Mathematics, 2008)The proof of the existence of a global connection in differential systems is generally a difficult task. Some authors use ...

Existence of homoclinic connections in continuous piecewise linear systems
Carmona Centeno, Victoriano; Fernández Sánchez, Fernando; García Medina, Elisabeth; Teruel Aguilar, Antonio Esteban (American Institute of Physics, 2010-03)Numerical methods are often used to put in evidence the existence of global connections in differential systems. The ...

Integral characterization for Poincaré half-maps in planar linear systems
Carmona Centeno, Victoriano; Fernández Sánchez, Fernando (Elsevier, 2021-12)The intrinsic nature of a problem usually suggests a first suitable method to deal with it. Unfortunately, the apparent ...
