“…In study [22], intermittency was classified as type I, type II, and type III in accordance with the Floquet multipliers. Types I, II, and III respectively correpond to the formation of cyclic-fold bifurcation, sub-critical Hopf bifurcation or Neimark-Sacker bifurcation, and sub-critical perioddoubling bifurcation [23]. Some other kinds of intermittency are type X, type V, on-off, eyelet, crisisinduced, and ring [23]- [29].…”
