Tableau Calculus for Dummett Logic Based on Present and Next State of Knowledge

16 pagesPublished: May 15, 2012

Abstract

In this paper we use the Kripke semantics characterization of Dummett logic to introduce a new way of handling non-forced formulas in tableau proof systems. We pursue the aim of reducing the search space by strictly increasing the number of forced propositional variables after the application of non-invertible rules. The focus of the paper is on a new tableau system for Dummett logic, for which we have an implementation. The ideas presented can be extended to intuitionistic logic and intermediate logics as well.

Keyphrases: automated theorem proving, Dummett Logic, tableau calculi
