Abstract
In this paper the new sets called minimal pgrω-open sets and maximal pgrω-closed sets in a topological space are introduced which are the pgrω-open sets and pgrω-closed sets respectively. The complement of minimal pgrω-open set is a maximal pgrω-closed set. Some properties of the maximal-semi-pgrw-open sets, minimal-semi-pgrw-closed sets, Minimal pgrw-continuous maps, Maximal pgrw-continuous maps and T_min−pgrw, T_max−pgrw, Min-T_pgrw, Max-T_pgrw-Spaces are studied.
