Hopf bifurcation in 3-dimensional polynomial vector fields

Research output: Contribution to journalArticleResearchpeer-review

Abstract

In this work we study the local cyclicity of some polynomial vector fields in R 3. In particular, we give a quadratic system with 11 limit cycles, a cubic system with 31 limit cycles, a quartic system with 54 limit cycles, and a quintic system with 92 limit cycles. All limit cycles are small amplitude limit cycles and bifurcate from a Hopf type equilibrium. We introduce how to find Lyapunov constants in R 3 for considering the usual degenerate Hopf bifurcation with a parallelization approach, which enables to prove our results for 4th and 5th degrees.
