Let L be a frame. We denoted the set of all regular ideals of cozL by rId(cozL) . The aim of this paper is to study these ideals. For a frame L , we show that rId(cozL) is a compact completely regular frame and the map jc : rId(cozL)→L given by jc (I)=⋁I is a compactification of L which is isomorphism to its Stone–Čech compactification and is proved that jc have a right adjoint rc : L →...
