Phase can be defined as a Hilbert transformation of a trajectory component, as the angle of a trajectory point into a special projection of the attractor, as a function that grows by 2 π every time the chaotic trajectory crosses some specific surface, or as the angle of the projected vector field into some subspace with respect to some rotation point

A chaotic set is always transitive through the flow. So, given a set of initial conditions, its evolution through the flow eventually reaches arbitrary open subsets of the original chaotic attractor. However, the conditional Poincaré map might not possess the transitive property. That is, given a set of initial conditions, its evolution through this map might not reach arbitrary open subsets of the special projections of the chaotic attractor; its dynamics stay confined to a subset of the attractor

r is considered to be rational. However, as shown in Ref. [23], PS, as defined by the boundedness of the phase difference, was found in two chaotic systems for a finite but very large time interval as r approaches an irrational. Therefore, although in this work we consider r to be rational, we should make the remark that, for the special situation such as that presented in Ref. [23], Eq. (6) can only be satisfied for a finite but large time if r is considered to be irrational

The intermittency observed in the phase difference is characterized as a usual intermittency by the alternation between a laminar regime and a burst regime. If the phase difference remains bounded in the interval [ 0, 〈 Δ φ 1 〉 ], we say that we have a laminar regime. If the phase difference leaves this interval, we have a burst, also known as phase slip. As one approaches the border between the PS and the non-PS region, the laminar regime in the phase difference becomes longer

The choice of these time intervals is not unique. It depends on what type of event one wants to identify in the system. A length-1 basic set is constructed by measuring time intervals between the occurrence of two events of the same type. A length-2 basic set is constructed by measuring the time interval between the occurrence of an event A and the occurrence of an event B, and then between the event B and finally the event A, and so on
