Canonical propositional Gentzen-type systems are systems which in addition to the standard axioms and structural rules have only pure logical rules with the subformula property, in...
While propositional modal logic is a standard tool, first-order modal logic is not. Indeed, it is not generally understood that conventional first-order syntax is insufficiently ex...
