Investigating soundness and completeness of verification calculi for imperative programming languages is a challenging task. Incorrect results have been published in the past. We t...
The theorem on loop formulas due to Fangzhen Lin and Yuting Zhao shows how to turn a logic program into a propositional formula that describes the program's stable models. In...
Abstract. We give an optimal (exptime), sound and complete tableaubased algorithm for deciding satisfiability for propositional dynamic logic. Our main contribution is a sound meth...
We present a sound and complete tableau calculus for the class of regular grammar logics. Our tableau rules use a special feature called automaton-labelled formulae, which are simi...
Abstract. We introduce a novel extension of propositional modal logic that is interpreted over Kripke structures in which a value is associated with every possible world. These val...
