4th Workshop on Hybrid Logics
LICS 2002 Affiliated Workshop
July 25th, 2002. Copenhagen, Denmark
Hybrid logic is a branch of modal logic in which it is possible to directly refer to worlds/times/states or whatever the elements of the (Kripke) model are meant to represent. Although they date back to the late 1960s, and have been sporadically investigated ever since, it is only in the 1990s that work on them really got into its stride.
It is easy to justify interest in hybrid logic on applied grounds, with the usefulness of the additional expressive power. For example, when reasoning about time one often wants to build up a series of assertions about what happens at a particular instant, and standard modal formalisms do not allow this. What is less obvious is that the route hybrid logic takes to overcome this problem (the basic mechanism being to add nominals --- atomic symbols true at a unique point --- together with extra modalities to exploit them) often actually improves the behavior of the underlying modal formalism. For example, it becomes far simpler to formulate modal tableau and resolution in hybrid logic, and completeness and interpolation results can be proved of a generality that is simply not available in modal logic. That is, hybridization --- adding nominals and related apparatus --- seems a fairly reliable way of curing many known weaknesses in modal logic.
HyLo@LICS is likely to be relevant to a wide range of people, including those interested in description logic, feature logic, applied modal logics, temporal logic, and labelled deduction. 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 from all the different fields just mentioned (and hopefully some others) in an attempt to explore 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 Hybrid Logics homepage. And do not hesitate to contact the workshop organisers for more information. We'd be delighted to tell you more. Contact details are given below.
We invite the contribution of research papers to the workshop. Please send electronically an extended abstract of up to 10 A4 size pages, in PostScript format to: email@example.com BEFORE the 26st of APRIL, 2002. Please note that all workshop contributors are required by the LICS organizers to register for FLoC 2002.
