本文讨论了符号动力系统的几乎周期点、回归点及混沌集。
Some properties of almost periodic points, recurrent points and chaotic sets in symbolic dynamical systems are given.
本文讨论了符号动力系统子移位的弱混沌，并得到拓扑熵为零的弱混沌子移位。
In this paper, we study weakly chaos on sub-shift of symbol dynamical system, and give a weakly chaotic sub-shift whose topological entropy is zero.
