拓扑动力系统中一类集合的推广

Some Generalizations of a Class of Sets in Topological Dynamical Systems

进一步讨论一类集合L(x1,x2),推广其定义;其次,研究推广后集合类的相关性质,并给出等度连续系统的一个刻画.最后,对集合L(x1,x2)与L(x1,x2,x3)之间的关系进行讨论,得到一个新的结果.

In this paper,we give further discussions about a class of sets L（x1,x2）.First,we generalize its definitions and study the relative properties of these generalized sets.Then we give a characterization of equicontinous systems.Finally,by discussing the relationship between L（x1,x2） and L（x1,x2,x3）,we obtain a new result.
