Concerning the frame of minimal prime ideals of pointfree function rings abstract

Let L be a completely regular frame and mathcal{R}L be the ring of continuous real-valued functions on L. We study the frame mathfrak{O}(Min(mathcal{R}L)) of minimal prime ideals of mathcal{R}L in relation to beta L. For Iinbeta L, denote by textit{textbf{O}}^I the ideal {alphainmathcal{R}Lmidcozalphain I} of mathcal{R}L. We show that sending I to the set of minimal prime ideals not containing textit{textbf{O}}^I produces a *-dense one-one frame homomorphism beta Ltomathfrak{O}(Min(mathcal{R}L)) which is an isomorphism if and only if L is basically disconnected.
