The decision problem is studied for fragments of second-order linear logic without modalities. It is shown that the structural rules of contraction and weakening may be simulated ...
In this paper we define a framework to introduce gradedness in Deontic logics through the use of fuzzy modalities. By way of example, we instantiate the framework to Standard Deont...
We outline a possible logic that will allow us to give a unified approach to reasoning about computational effects. The logic is given by extending Moggi’s computational λ-cal...
We Imbed Into a first order logic a representation language that combines atemporal knowledge with time stamps in a hierarchical fashion. Each time structure contains its own chro...
Since belief revision deals with the interaction of belief and information over time, branching-time temporal logic seems a natural setting for a theory of belief change. We propo...
