HIDDEN ATTRACTORS IN 4D DISCONTINUOUS MEMRISTOR OSCILLATORS The so-called multiple focus center bifurcation (MFCC) that leads to the appearance of a topological sphere foliated by stable periodic orbits was recently investigated in discontinuous 4D memristors oscillators [1]. To continue with this work, we study the points where the MFCC bifurcation is degenerate. Starting from previous analytical results that guarantee the existence of a saddle-node bifurcation curve of periodic orbits that emanate from such points of degeneration, a numerical continuation of the saddle-node bifurcation curves will be done. Getting a region on a certain parameter plane, where a stable limit cycle coexist with a stable equilibrium point; in fact, such a stable limit cycle is known as a hidden attractor.
