Unravelling the dynamical richness of 3D canonical memristor oscillators

In the study of the dynamical richness of canonical memristor oscillators, two main drawbacks are to be overcome. First, the dimensional issue, since at least a 3D dynamical system must be analyzed; secondly, one must deal with discontinuous models, when a piecewise linear characteristics for the memristor is adopted. Such discontinuity arises after taking derivatives of the piecewise linear characteristics of the memristor, in order to work with state variables within the realm of currents and voltages.
