This paper proposes some variants of Temporal Defeasible Logic (TDL) to reason about normative modifications. These variants make it possible to differentiate cases in which, for ...
Temporal logics of knowledge are useful for reasoning about situations where the knowledge of an agent or component is important, and where change in this knowledge may occur over...
We consider unranked trees, that have become an active subject of study recently due to XML applications, and characterize commonly used fragments of firstorder (FO) and monadic ...
—Data trees are trees in which each node, besides carrying a label from a finite alphabet, also carries a data value infinite domain. They have been used as an abstraction mode...
Abstract. We investigate the computational behaviour of `two-dimensional' propositional temporal logics over (N, <) (with and without the next-time operator ?) that are cap...
