4th Workshop on Hybrid Logics

LICS 2002 Affiliated Workshop
July 25th, 2002. Copenhagen, Denmark

Modal logic suffers from a certain asymmetry: even though the basic semantic notion in modal languages is truth at a state, classical modal logics lack the expressive power to talk about the states themselves. Whether we think of states as intervals, geometric points, nodes in a feature structure, or individuals in a description, this is a genuine weakness.

Hybrid Logics are modal languages which use "terms as formulas". Although they date back to the late 1960s, the last three years have seen a resurgence of interest, with new results in expressivity, interpolation, complexity, and proof techniques. It has also become clear that hybrid logics offer a theoretical framework for uniting the work of a surprisingly diverse range of research traditions.

This workshop is likely to be relevant to a wide range of people, including those interested in description logic, feature logic, modal logics for information systems, temporal logic, and labelled deduction for modal logic. Moreover, if you have an interest in the work of the late Arthur Prior, note that this workshop is devoted to exploring ideas he first introduced 30 years ago --- it will be an ideal opportunity to see how his ideas have been developed in the intervening period.

In this workshop we hope to bring together researchers and students from all the different fields just mentioned (and hopefully some others) in an attempt to explore just what they all have (and do not have) in common. If you're unsure whether your work is of relevance to the workshop, please check out the newly opened Hybrid Logic Site:


And do not hesitate to contact the workshop organisers for more information. We'd be delighted to tell you more.
