Beschreibung:
In this paper examples are given to show thats-regular ands-normal are independent; thats-normal, ands-regular are not semi topological properties; and that(S(X),E(X))need not be semi-T1even if(X,T)is compact,s-normal,s-regular, semi-T2, andT0. Also, it is shown that for each space(X,T),(S(X),E(X)),(S(X0),E(X0)), and(S(XS0),E(XS0))are homeomorphic, where(X0,Q(X0))is theT0-identification space of(X,T)and(XS0,Q(XS0))is the semi-T0-identification space of(X,T), and that if(X,T)iss-regular andR0, then(S(X),E(X))is semi-T2.
