Abstract

In this note, we study the operation of Sasaki hook within the setting of quantum cylindric algebras by introducing cylindric quasi-implication algebras. It is first demonstrated that every quantum cylindric algebra can be converted into a cylindric quasi-implication algebra and conversely that every cylindric quasi-implication algebra gives rise to a quantum cylindric algebra. These constructions are then shown to induce an isomorphism between the category CQIA\mathbf{CQIA} of cylindric quasi-implication algebras and the category QCA\mathbf{QCA} of quantum cylindric algebras. We then give two alternative constructions of a cylindric orthoframe XAX_A from a cylindric quasi-implication algebra AA. The first construction of XAX_A arises via the non-zero elements of AA and generalizes the construction given by Harding in the setting of cylindric ortholattices from the perspective of MacNeille completions. The second construction of XAX_A arises via the proper filters of AA and generalizes the construction given by McDonald in the setting of cylindric ortholattices from the perspective of canonical completions.
