| Abstract: | We discuss topology space is several tantamount scores of S-connectedness,at the same time we also argue S-connected subset and its quality.And we point out the quality of the sequential space and connected space.We gain the results as follows: X is S-connected space,then X is an image of a connected sequential space under a continuous mapping,and X is an image of a connected sequential space under a sequential continuous mapping,and X is a image of a connected sequential space under a continuous sequential covering mapping. |
