Abstract:

Birkhoff and non-Birkhoff types of periodic orbits are defined in circle maps. The dynamical order relation of non-Birkhoff periodic orbits (NBOs) with period longer than or equal to three is proved. Braids are constructed for NBOs, and a lower bound for the topological entropy is derived.
