Revisiting Interpolation in Relevant Logics

Logic 2025-12-01 v1 Logic in Computer Science

Abstract

There are exactly two maximal schematic extensions of the relevant logic R with the variable sharing property. We establish that one of them has a strong form of interpolation for deducibility, thereby giving an example of a well-known relevant logic with interpolation.
