Publication Detail
Positive Fragments of Relevance Logic and Algebras of Binary Relations
Abstract
We prove that algebras of binary relations whose similarity type includes intersection, union, and one of the residuals of relation composition form a non-finitely axiomatizable quasivariety and that the equational theory is not finitely based. We apply this result to the problem of the completeness of the positive fragment of relevance logic with respect to binary relations.
