Consider any logical system, what is its natural repertoire of logical operations? This question has been raised in particular for first-order logic and its extensions with genera...
Traditional security analyses are often geared towards cryptographic primitives or protocols. Although such analyses are absolutely necessary, they do not provide much insight for...
The evolution of Description Logics (DLs) and Propositional Dynamic Logics produced a hierar chy of decidable logics with multiple maximal el ements. It would be desirable to ...
The aim of the present paper is to provide a metalogical systematisation in the area of deontic action logic based on Boolean algebra. Differences among the systems in question lie...
Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability of different semantics naturally raises the que...
