Research on the related properties of(J)sn-Fréchet-Urysohn space and(J)sn-(J)-Fréchet-Urysohn space

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.
Keywords：(J)-sequential space(J)-neighborhood space(J)sn-sequential space.(J)sn-Fréchet-Urysohn space(J)sn-(J)-Fréchet-Urysohn spacepseudo open mapping
