MINIMAL QUASI-F COVERS OF υX

Abstract

We show that if X is a space such that βQF (X) = QF (βX) and each stable Z(X)#-ultrafilter has the countable intersection property, then there is a homeomorphism hX : υQF (X) −→ QF (υX) with rX = ΦυX ◦ hX . Moreover, if βQF (X) = QF (βX) and υE(X) = E(υX) or υΛ(X) = Λ(υX), then υQF (X) = QF (υX).
