摘 要: 本文在实数集 R 上所有拓扑结构中,选出使数列收敛的意义等价于欧氏拓外的一类拓扑,称之为数列拓扑.讨论了这类拓扑的可分,连通、分离、紧致,可数等拓扑性质.举出了非欧氏拓扑的数列拓扑的例子. In this paper,a class of topologies,that is equivalent to E-topology in the mean- ing of sequence convergence,is selected from other topological structures on real number set R and it is called Sequence Topology.Some topological properties,for example,separableness,conneetiveness,separation compactness countableness,are dis- cussed for such topologies.A example of sequence topology of non-E-topology is given.
