Transition to chaos in a dissipative standardlike map

초록

We study the transition to chaos caused by overlap of resonances in a dissipative standardlike map exhibiting recurrence of invariant circles. In particular, the effects of the recurrence on the structure of a critical line at which the motion is always mode locked are investigated. When there is no recurrence of invariant circles, a smooth critical line exists. In the recurrence case, however, the critical line is folded back and has discontinuous parts. At this line the mode-locked intervals trace a folded devils staircase with isolated parts. Scaling behavior of the complementary set to the folded staircase is also discussed. © 1992 The American Physical Society.
