Functional monadic ortholattices and locally finite $\sigma$-free polyadic ortholattices

Logic 2025-06-11 v1

Abstract

In this paper, we show that every monadic ortholattice is isomorphic to a functional one, thereby resolving a recent question posed by Harding. We then study certain substitution-free reducts of the polyadic ortholattices, which we call locally finite σ\sigma-free polyadic ortholattices, and provide an analogous functional representation result.
