We also study the Pairwise PN strongly irresolvable spaces .The conditions under which pairwise PN strongly irresolvable spaces become pairwise PN first category spaces and pairwise PN Baire spaces are also investigated.   2020 2020 50 57 10.54216/IJNS.0120101 https://www.americaspg.com/articleinfo/21/show/630
