摘要
研究了(J)sn-(J)-Fréchet-Urysohn空间,并且结合(J)sn-序列空间和(J)sn-Fréchet-Urysohn空间的概念,讨论了它们之间的等价关系和一些相关性质,例如和伪开映射之间的关系等.最后,讨论了这些空间和理想收敛中其他空间之间的关系.
Abstract
In this paper,we continue research the concept of(J)sn-(J)-Fréchet-Urysohn space.After that,according to the concept of(J)sn-sequential space and(J)sn-Fréchet-Urysohn space,we discuss their equivalent relationship and their related properties such as the relationship with pseudo open mapping and so on.In the end,we discuss the relationship between these spaces and another spaces in ideal convergence.
