Abstract

Let Rα := {r ∈ ℝ : coz(α − r) ≠ → p} for every α ∈ 𝓡(L). The ring 𝓒c (L) is introduced as a pointfree version of the subring 𝓒c(X) of C(X) by Rα. In this paper, we show that 𝓒c(X) is a z-good ring and every radical ideal in it is an absolutely convex ideal. Also, we study this result which for any frame L, there exists a zero-dimensional frame M, which is a continuous image of L and 𝓒c(L) ≅ 𝓒c(M).
