# ON QUASI-gsp-NORMAL SPACES AND πgsp-CLOSED SETS *

The Global J. Of Appl.Math. & Math.Sci., 01/2009; Vol.2(Nr.1-2):65-71.

ABSTRACT

In this paper, we introduce the concept of πgsp-closed sets as weak form of πg-closed sets due to Dontchev and Noiri(2000).We also introduce the notion of quasi-gsp-normal spaces.By using πgsp-closed sets we obtain a characterization and preservation theorems of quasi-gsp-normal spaces.

ABSTRACT: Some properties of quasi-normal spaces are studied. In particular, a few results on mildly normal spaces by M. K. Singal and A. R. Singal [Kyungpook Math. J. 13, 27-31 (1973; Zbl 0266.54006)] and T. Noiri [ibid. 225-228 (1973; Zbl 0283.54011)] are improved.
