[- Apologies for multiple copies -] DEADLINE EXTENSION: New deadline for submissions of regular papers on **Monday, January 21** CMCS 2008 9th International Workshop on Coalgebraic Methods in Computer Science http://www.cwi.nl/projects/cmcs08/ Budapest, Hungary April 4-6, 2008 Key Note Speaker: Dexter Kozen (to be confirmed) Invited Speakers: Stefan Milius and Dirk Pattinson Important Dates Extended deadline for submission of regular papers: January 21, 2008 Notification of acceptance of regular papers: February 11, 2008. Final version for the preliminary proceedings: February 18, 2008. Deadline for submission of short contributions: March 10, 2008. Notification of acceptance of short contributions: March 17, 2008. The workshop will be held in conjunction with the 11th European Joint Conferences on Theory and Practice of Software ETAPS 2008 March 29 - April 6, 2008 Programme Committee Jiri Adamek (chair, Braunschweig), Corina Cirstea (Southampton), Neil Ghani (Nottingham), H. Peter Gumm (Marburg), Bart Jacobs (Nijmegen), Clemens Kupke (co-chair, Amsterdam), Alexander Kurz (Leicester), Ugo Montanari (Pisa), Larry Moss (Indiana), John Power (Bath), Jan Rutten (Amsterdam), Lutz Schröder (Bremen), Tarmo Uustalu (Tallinn), Yde Venema (Amsterdam), Hiroshi Watanabe (Osaka). Submissions Two sorts of submissions will be possible this year: Papers to be evaluated by the programme committee for inclusion in the ENTCS proceedings: These papers must be written using ENTCS style files and be of length no greater than 20 pages. They must contain original contributions, be clearly written, and include appropriate reference to and comparison with related work. If a submission describes software, software tools, or their use, it should include all source code that is needed to reproduce the results but is not publicly available. If the additional material exceeds 5 MB, URL's of publicly available sites should be provided in the paper. Short contributions: These will not be published but will be compiled into a technical report of the Technical University of Braunschweig. They should be no more than two pages and may describe work in progress, summarise work submitted to a conference or workshop elsewhere, or in some other way appeal to the CMCS audience. Both sorts of submission should be submitted in postscript or pdf form as attachments to an email to cmcs08@cwi.nl. The email should include the title, corresponding author, and, for the first kind of submission, a text-only one-page abstract. After the workshop, we expect to produce a journal proceedings of extended versions of selected papers to appear in Theoretical Computer Science. For more information, please write to cmcs08@cwi.nl
