Almost p-normal, mildly p-normal spaces and some functions

The aim of this paper is to obtain some characterizations of almost p-normal spaces and mildly p-normal spaces and to improve the preservation theorems of p-normal spaces and mildly p-normal spaces established by Navalagi [P-normal, almost p-normal and mildly p-normal spaces.
