The Logics of Individual Medvedev Frames

Abstract

Let nn-Medvedev's logic MLn\mathbf{ML}_n be the intuitionistic logic of Medvedev frames based on the non-empty subsets of a set of size nn, which we call nn-Medvedev frames. While these are tabular logics, after characterizing nn-Medvedev frames using the property of having at least nn maximal points, we offer a uniform axiomatization of them through a Gabbay-style rule corresponding to this property. Further properties including compactness, disjunction property, and structural completeness of MLn\mathbf{ML}_n are explored and compared to those of Medvedev's logic ML\mathbf{ML}.
