Abstract
In this paper, we introduce a new class of normal space called, (1, 2)*-quasi ï¨-normal space. The relationships among (1, 2)*-normal, (1, 2)*-quasi ï¨-normal, mildly (1, 2)*-normal, (1, 2)*-quasi ï¡-normal, (1, 2)*-mildly ï¡-normal, (1, 2)*-ï¡-normal and mildly (1, 2)*-ï¨-normal spaces are investigated. Moreover, we introduce some closed functions such as (1, 2)â??-ï°gï¨-closed and almost (1, 2)â??-ï°gï¨-closed. Utilizing (1, 2)â??-ï°gï¨-closed sets and some functions, we obtain some characterizations and preservation theorems for (1, 2)*-quasi ï¨-normal spaces.
