EXTENDED DEADLINE FOR CMCS'2000: Due to the Y2K bug scare the deadline for submissions to CMCS'2000 is extended to 17 January 2000!!!!! The other dates of the following CFP do not change: **************************************************************************** ****** C A L L F O R P A P E R S for the WORKSHOP ON COALGEBRAIC METHODS IN COMPUTER SCIENCE (CMCS'2000) Scope State-based dynamical systems as found throughout computing science are traditionally described as transition systems or certain kinds ofautomata. During the last decade, it has become increasingly clear that such systems can be captured uniformly as so-called ``coalgebras'' (which are the formal dual of algebras). Coalgebra is beginning to develop into a field of its own, with its own proof-methods (involving bisimulations and invariants). This workshop will be devoted to both an introduction to basic coalgebraic notions and techniques, and also to some recent advances in the theory of coalgebras. We are looking for participants and contributed talks to this informal workshop on both the theory and the use of coalgebras in computer science. The workshop will consist of two days, preceding the ETAPS conference (25-26 March, 2000) at the Technical University of Berlin. More information regarding submissions is given below. The scope of the meeting includes the following themes: - the theory of coalgebras (including set theoretic and categorical approaches); - coalgebras as computational and semantical models (for programming languages, dynamic systems, etc.); - coalgebras in (functional, object-oriented, concurrent) programming; - coalgebras and data types; - (coinductive) definition and proof principles for coalgebras (with bisimulations or invariants); - coalgebras and (hidden-sorted) algebras; - coalgebraic specification and verification; - coalgebras and (modal) logic Organization: Bart Jacobs (Nijmegen), Horst Reichel(Dresden), Jan Rutten (CWI, Amsterdam) and Larry Moss (Bloomington, IN). Program Committee: H. Peter Gumm (Marburg), Bart Jacobs (Nijmegen), Ugo Montanari (Pisa), Larry Moss (Bloomington, IN), Ataru T. Nakagawa (Tokyo), John Power (Edinburgh), Horst Reichel (Dresden), Jan Rutten (CWI, Amsterdam). Submissions The following dates are important for submission to the ENTCS volume. - 3 January 2000: deadline for submissions. - 11 February 2000: notification of acceptance. - 3 March 2000: final version. - 25-26 March 2000: workshop, where a printed version of the ENTCS issue will be available for participants. - (25 March - 2 April, 2000: ETAPS conference). The ideal submission is not longer than 20 pages, and gives a clear exposition of the relevant ideas. It can be sent by email to: Horst Reichel, or by ordinary mail to: Horst Reichel TU Dresden, Faculty of Computer Science Institute: Theoretical Computer Science D-01062 Dresden Germany The informations will be actualized on the following web page: http://wwwtcs.inf.tu-dresden.de/~reichel/cmcs.html
