1) Y is superregular in X

2) Y is strongly regular in X

3) Y is regular in X

4) Y is δ-regular in X

5) Y is strongly normal in X
Y在X中强正规
1.
It is proved that if Y is Ti in X,then Y is Ti-1 in X,where i is from 3 to 4;When Y is a open and closed subspace of X,Y is normal in X if and only if Y is quasi-normal in X if and only if Y is strongly normal in X.
本文讨论了拓扑空间的相对分离性,证明了若Y在X中是Ti的,则Y在X中是Ti-1(i=3,4);当Y是X的既开又闭子空间时,Y正规、Y在X中正规、Y在X中拟正规和Y在X中强正规是等价的。
6) Y is strongly δ-normal in X
Y在X中强δ-正规
