Abstract

If f : XX is a continuous map and xX, we say that y is a limit point for the associated dynamical system with initial value x, or y is an ω limit point of x, when y is a limit point of the orbit sequence {f n (x) : nT} where T is the set of nonnegative integers. This means that the sequence enters every neighborhood of y infinitely often. That is, for any open set U containing y, the entrance time set N(x,U) = {nT : f n (x) ∈ U} is infinite.
