Bounding the number of limit cycles in piecewise linear differential systems: methodology and worked examples

Victoriano Carmona, Fernando Fernández-Sánchez, Douglas D. Novaes

In 2012, Huan and Yang introduced the first piecewise linear differential system with two zones separated by a straight line having at least three limit cycles, serving as a counte…
