Almost Normal Spaces and Closed Sets

2016 International Journal of Science and Research (IJSR)  
In this paper, we introduce the notion of gg  -closed and rgg  -closed sets in topological spaces and investigate some of their properties. Further, utilizing gg  -closed and rgg  -closed sets, we obtain characterizations and preservation theorems for g normal, almost g  -normal and mildly g  -normal spaces.
