Cut-free Display Calculi for Relational Algebras

Rajeev Gor?e

Abstract We give a propositional cut-free Gentzen-like calculus for relation algebras using Belnap's Display Logic. The calculus extends trivially to cater for a large class of axiomatic extensions of relation algebras where the axioms appear as purely structural rules. The calculus incorporates features of Relevant Display Logics and Modal Display Logics, highlighting the relationship between relation algebras and substructural logics.
