摘要
引入了一类新的拓扑空间,称为B闭空间.B闭空间是重要空间S闭空间的推广,是H(i)空间的特殊情形,但在极不连通的空间中,B闭空间、S闭空间、H(i)空间彼此等价.
In this paper,the new concept of so-called B-closed space in topological spaces is introduced. B-closed space is the generalization of S-closed space,and it is the special state of space . B-closed space,S-closed space and space are equivalent in extremely disconnected spaces.
