We present the rst implementation of a theorem prover which runs on a smart card. The prover is written in Java and implements a dual tableau calculus.1 Due to the limited resource...
Pinto and Reiter have argued that the Situation Calculus, improved with time handling axioms, subsumes the features of linear time temporal formalisms such as Event Calculus and I...
We investigate a modification of the sequent calculus which s a first-order proof into its abstract deductive structure and a unifier which renders this structure a valid proof. We...
Based on natural deduction, Pure Type Systems (PTS) can express a wide range of type theories. In order to express proof-search in such theories, we introduce the Pure Type Sequent...
Our goal is to identify families of relations that are useful for reasoning about software. We describe such families using decidable quantifier-free classes of logical constraints...
