| Abstract: | This paper discusses the knowledge of topological space,the definition of closed sets and the application knowledge of convergence according to open set. We analyze how to define the closed sets by the convergence of point sequence in order to define the way of topological space,and apply this way to specific examples,and compare it with the commonly used definition ways in the existing materials. We conclude that the closed sets can be used to define the topological space. |
