Methods for Modalities 6
Copenhagen, Denmark. November 12-14, 2009
Photos
Photos from the event taken by Jørgen Villadsen are available.
Program
The full workshop program is available.
Theme
The workshop series Methods for Modalities (M4M) aims to bring together researchers interested in developing algorithms, verification methods and tools based on modal logic. Here the term "modal logic" is conceived broadly, including description logic, guarded fragments, conditional logic, temporal and hybrid logic, etc.
Special Features
To stimulate interaction and transfer of expertise, M4M will feature a number of invited talks by leading scientists, research presentations aimed at highlighting new developments, and submissions of system demonstrations. We strongly encourage young researchers and students to submit papers, especially for experimental and prototypical software tools which are related to modal logics.

Mini-Course: Autumn School on Modal Logic
M4M-6 will be preceded by a two-day mini-course called "Autumn School on Modal Logic" aimed at preparing PhD students and other researchers for participation in the workshop. The autumn school will be taught by Carlos Areces, Patrick Blackburn, Valentin Goranko, Renate Schmidt, and Carsten Schürmann. Consult the autumn school home page for further information:

http://hylocore.ruc.dk/m4m6school.html

The autumn school is associated with the FIRST research school (http://first.dk).

Submissions
Authors are invited to submit papers in the following three categories.
  • Regular papers up to 15 pages, describing original research.
  • System descriptions of up to 12 pages, describing new systems or significant upgrades of existing ones.
  • Presentation-only papers, describing work recently published or submitted (no page limit). These will not be included in the proceedings, but pre-prints or post-prints can be made available to participants.

Submissions should be made via EasyChair at the following address:

http://www.easychair.org/conferences/?conf=m4m6

Final versions of accepted papers will be published online in an Elsevier ENTCS volume. A preliminary version of the proceedings will be provided at the workshop. Instructions for preparing your paper can be found at the web page of ENTCS (http://www.entcs.org). Please remember to use the file prentcsmacro.sty that is dedicated to the M4M proceedings.

The Call for Papers is available.

Venue and Travelling
M4M-6 will take place at the IDA Conference Center on Kalvebod Brygge 31-33 in the center of Copenhagen. The conference center is located 1 km from Copenhagen Central Station. There is a direct train connection between Copenhagen Airport and Copenhagen Central Station. The train is of type "Re". Copenhagen Central Station is called "Hovedbanegården" or sometimes "København H" in Danish. The following map shows how to get from the central station to the workshop venue:
