Abstract:
It is shown in this paper that for $P = {T_2}$ or $P = {T_3}$ every locally $P$-closed space is a retract of a rim $P$-closed, locally $P$-closed space by an open, perfect retraction map. From this it follows that there exist noncompact, rim $H$-closed, $H$-closed spaces and noncompact, rim $R$-closed, $R$-closed spaces.References
