Announcement for the 8th International Conference on Relational Methods in Computer Science (RelMiCS 8) in combination with the COST 274 / TARSKI Workshops and the 3rd International Workshop on Applications of Kleene Algebra February 22-26, 2005 St. Catharines, Ontario, Canada The purpose of this meeting is to bring together researchers from various subdisciplines of Computer Science and Mathematics who use the calculus of relations and/or Kleene algebra as methodological and conceptual tools in their work. The relational calculus originated with Tarski's abstract algebraic treatment of binary relations in 1941. Kleene Algebra is a related algebraic system. It was first introduced by Kleene in 1956 and further developed by Conway in 1971. Topics of this conference include but are not limited to: - Relation, Cylindric, Fork and Kleene Algebras - Relational proof theory and decidability issues - Relational representation theorems - Applications to programming, databases and analysis of data, such as: * Semantics of programming languages, program verification, specification and development and program analysis * Assertion calculi, modal and dynamic logic, interval and temporal logic * Duration calculus and timed automata * Process and network algebras * Modeling real world situations * Relational reasoning in qualitative physics and cognitive science * Knowledge acquisition, preference modeling, and scaling methods - Computer systems for relational knowledge representation Previous RelMiCS meetings were held in 1) Dagstuhl, Germany (1994) 2) Parati, Brazil (1995) 3) Hammamet, Tunesia (1997) 4) Warsaw, Poland (1998) 5) Québec, Canada (2000) 6) Oisterwijk, The Netherlands (2001) 7) Malente, Germany (2003) A call for papers will follow.
