Stratified Least Fixpoint Logic
Compton, K.J., Stratified least fixpoint logic, Theoretical Computer Science 131 (1994) 95-120. Stratified least jixpoint logic, or SLFP, characterizes the expressibility of stratified logic programs and, in a different formulation, has been used as a logic of imperative programs. These two formulations of SLFP are proved to be equivalent. A complete sequent calculus with one infinitary rule is...
متن کاملEvidence for Fixpoint Logic
For many modal logics, dedicated model checkers offer diagnostics (e.g., counterexamples) that help the user understand the result provided by the solver. Fixpoint logic offers a unifying framework in which such problems can be expressed and solved, but a drawback of this framework is that it lacks comprehensive diagnostics generation. We extend the framework with a notion of evidence, which ca...
متن کاملCompleteness for Coalgebraic Fixpoint Logic
We introduce an axiomatization for the coalgebraic fixed point logic which was introduced by Venema as a generalization, based on Moss’ coalgebraic modality, of the well-known modal mucalculus. Our axiomatization can be seen as a generalization of Kozen’s proof system for the modal mu-calculus to the coalgebraic level of generality. It consists of a complete axiomatization for Moss’ modality, e...
متن کاملA Abstraction in Fixpoint Logic
ion in Fixpoint Logic SJOERD CRANEN, MACIEJ GAZDA, WIEGER WESSELINK and TIM A.C. WILLEMSE, Eindhoven University of Technology We present a theory of abstraction for the framework of parameterised Boolean equation systems, a firstorder fixpoint logic. Parameterised Boolean equation systems can be used to solve a variety of problems in verification. We study the capabilities of the abstraction th...
متن کاملGames for Topological Fixpoint Logic
Topological fixpoint logics are a family of logics that admits topological models and where the fixpoint operators are defined with respect to the topological interpretations. Here we consider a topological fixpoint logic for relational structures based on Stone spaces, where the fixpoint operators are interpreted via clopen sets. We develop a game-theoretic semantics for this logic. First we i...
