Abstract
In this paper, we introduce a new pointfree version of the ring Cc (X), denoted by Cc (L). This construction is defined via
Rα = { r ∈ R: coz(α − r) \neq ⊤ }, for α ∈ R (L),
where coz(·) denotes the cozero element. Additionally, we introduce the concept of CP-frames, examine their relationship with P-frames, and provide alternative characterizations of CP-frames. We also present several properties and characterizations of CP-frames.
