In this paper the machinery of Hybrid Logic and the logic of public announcements are merged. In order to bring the two logics together properly the underlying hybrid logic has be...
Sound and complete axiomatizations are provided for a number of different logics involving modalities for knowledge and time. These logics arise from different choices for various ...

We observe that the known fact that the difference logic and the hybrid logic with universal modality have the same expressive power on Kripke frames can be strengthened for a far ...
The combination of first-order epistemic logic and formal cryptography offers a potentially very powerful framework for security protocol verification. In this article, we addre...
Building on a simple modal logic of context, the paper presents a dynamic logic characterizing operations of contraction and expansion on theories. We investigate the mathematical...
