摘要:Summary: {\it D. Andrijevi\'c} [Mat. Vesn. 38, 24-32 (1986; Zbl 0604.54002)] introduced the class of semi-preopen sets in topological spaces. Since then many authors including Andrijevi\'c have studied this class of sets by defining their neighborhoods, separation axioms and func...

摘要:The authors, using preopen sets, define new separation axioms called almost $p$-regularity, $p$-complete regularity and almost $p$-complete regularity. They show that almost $p$-regular spaces are regular open hereditary, productive and invariant under almost continuous almost op...

摘要:Summary: Almost $s$-completely regular spaces have been defined by using semicontinuous maps introduced by {\it N. Levine} [Am. Math. Mon. 70, 36--41 (1963; Zbl 0113.16304)]. Among other things it is proved that (i) almost $s$-complete regularity is open hereditary; (ii) if $f:X\...

摘要:Summary: We introduce a new class of functions called rarely $\alpha gs$-continuous functions and investigate some of its fundamental properties.

摘要:The authors introduce and study two new classes of topological spaces, called semi-generalized-regular and semi-generalized-normal spaces. Here a set $A$ is semi-open in $(X,\tau)$ if $A\subset \text{cl}(\operatorname {int} A)$; the complement of a semi-open set is a semi-closed ...
