Subharmonic entrainment and limit cycle modulation by high frequency excitation: A Renormalization group approach

Somnath Roy, Debapriya Das, Dhruba Banerjee

In this article, we explore the possibility of a sub-harmonic $(1:2)$ entrainment and supercritical Hopf bifurcation in a van der Pol-Duffing oscillator that has been excited by…
