Jørgen Villadsen (Technical University of Denmark, jv@imm.dtu.dk)

WORKSHOP PURPOSE:

Hybrid logic is a branch of modal logic allowing direct reference
to worlds/times/states. It is easy to justify interest in hybrid
logic on the grounds of applications as the additional expressive
power is very useful. In addition, hybrid-logical machinery improves
the behaviour of the underlying modal formalism. For example, it
becomes considerably simpler to formulate modal proof systems, and
one can prove completeness and interpolation results of a
generality that is not available in orthodox modal logic.

The topic of the HyLo workshop of 2007 is not only standard
hybrid-logical machinery like nominals, satisfaction operators, and
the downarrow binder, but generally extensions of modal logic that
increase its expressive power.

The workshop HyLo 2007 will be relevant to a wide range of people,
including those interested in description logic, feature logic,
applied modal logics, temporal logic, and labelled deduction. The
workshop continues a series of previous workshops on hybrid logic,
most recently the LICS-affiliated HyLo 2006
(http://hylomol.ruc.dk/HyLo2006/). The workshop aims to provide a
forum for advanced PhD students and researchers to present and
discuss their work with colleagues and researchers who work in the
broad subject areas represented at ESSLLI.

For more general background on hybrid logic, and many of the key
papers, see the Hybrid Logics homepage (http://hylo.loria.fr/).

SUBMISSION DETAILS:

We invite the contribution of papers reporting new work from
researchers interested in hybrid logic. Papers should not
exceed 10 pages including references. A paper must be submitted
as a PDF file and the font size must be at least 10 pt when
printed on A4 paper. It is recommended that the LaTeX "article"
style is used. Please use the HyLo 2007 submission page
(http://www.easychair.org/HyLo2007/), handled by the EasyChair
conference system, to submit papers. The accepted papers will
appear in the workshop proceedings published by ESSLLI.
One author for each accepted paper must attend the workshop in
order to present the paper. It is planned to publish revised
versions of the accepted papers in a special issue of
Journal of Logic, Language and Information.

WORKSHOP FORMAT:

The workshop is part of ESSLLI and is open to all ESSLLI
participants. It will consist of five 90-minute sessions held over
five consecutive days in the first week of ESSLLI. There will be
2 or 3 slots for paper presentation and discussion per session.
On the first day the workshop organizers will give an introduction
to the topic.

INVITED SPEAKERS:

Balder ten Cate (University of Amsterdam, The Netherlands)
Ian Hodkinson (Imperial College, UK)

LOCAL ARRANGEMENTS:

All workshop participants including the presenters will be required
to register for ESSLLI. The registration fee for authors presenting
a paper will correspond to the early student/workshop speaker
registration fee. Moreover, a number of additional fee waiver grants
will be made available by the ESSLLI local organizing committee on
a competitive basis and workshop participants are eligible to apply
for those. There will be no reimbursement for travel costs and
accommodation. Workshop speakers who have difficulty in finding
funding should contact the local organizing committee to ask for
the possibilities for a grant.
