New insights to the Hide-Skeldon-Acheson dynamo

Abstract Full Text(HTML) Figure(6) Related Papers Cited by
  • The present work is devoted to giving new insights into the Hide-Skeldon-Acheson (HSA) dynamo. The paper discusses the locally and globally asymptotical stability of the equilibrium. All orbits of the system are proved to be bounded. The existence of periodic orbits is proved by the generalized Melnikov method. The paper proves rigorously that Hopf bifurcation occurs and gives the formulae to determine the direction, stability and period of bifurcating periodic solutions. Finally, the paper investigates the coexistence of three types of attractors: equilibria, hidden periodic attractors and hidden chaotic attractors.Note: Author's current affiliation "Qiuzhen College, Tsinghua University, Beijing, China" is added.
