Free Variable Tableaux for Propositional Modal Logics
نویسندگان
چکیده
Free-variable semantic tableaux are a well-established technique for first-order theorem proving where free variables act as a meta-linguistic device for tracking the eigenvariables used during proof search. We present the theoretical foundations to extend this technique to propositional modal logics, including non-trivial rigorous proofs of soundness and completeness, and also present various techniques that improve the efficiency of the basic naive method for such tableaux.

We present a sound, complete, modular and lean labelled tableau calculus for many propositional modal logics where the labels contain \free" and \universal" variables. Our \lean" Prolog implementation is not only surprisingly short, but compares favourably with other considerably more complex implementations for modal deduction.

متن کاملTableaux for Regular Grammar Logics of Agents Using Automaton-Modal Formulae
We present sound and complete tableau calculi for the class of regular grammar logics and a class eRG of extended regular grammar logics which contains useful epistemic logics for reasoning about beliefs of agents. Our tableau rules use a special feature called automaton-modal formulae which are similar to formulae of automaton propositional dynamic logic. Our calculi are cut-free and have the ...
متن کاملModal Logics with Hard Diamond-Free Fragments
We investigate the complexity of modal satisfiability for certain combinations of modal logics. In particular we examine four examples of multimodal logics with dependencies and demonstrate that even if we restrict our inputs to diamond-free formulas (in negation normal form), these logics still have a high complexity. This result illustrates that having D as one or more of the combined logics,...
متن کاملA Uniform Tableaux Method for Nonmonotonic Modal Logics
We present a semantic tableaux calculus for propositional nonmonotonic modal logics, based on possible-worlds characterisations for nonmonotonic modal logics. This method is parametric with respect to both the modal logic and the preference semantics, since it handles in a uniform way the entailment problem for a wide class of nonmonotonic modal logics: McDermott and Doyle's logics and ground l...
