KE-tableaux for intuitionistic propositional logic

Authors

Abstract

KE-tableaux are generalized to intuitionistic propositional logic by means of labeled signed formulas and constraints between labels, so that the resulting system closely mimics countermodel construction in the relational semantics. To improve on proof-search, we further endow the system with free-variables and show some of its basic properties: soundness, completeness and termination.
