 作者：G.B. Navalagi 来源：[J].Int. J. Math. Math. Sci., 2002, Vol.29 (2), pp.85-98ZBMATH 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...

Roum.(IF 0.419), 1990, (4), pp.317-326ZBMATH 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...

Soc., New Ser., 1997, Vol.64 (1-4), pp.1-4ZBMATH 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\...  作者：M. Caldas , G.B. Navalagi , R.K.

Jafari , G.B. Navalagi 来源：[J].Demonstr. Math., 2002, Vol.35 (2), pp.415-421ZBMATH 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 ...
