3rd workshop on Geometric and Topological Methods in Concurrency GETCO 2001 hosted by Concur 2001, and Aalborg University Venue: Aalborg University, Denmark Conference dates: CONCUR: August 21-24, 2001 GETCO: August 25, 2001 2nd Call for papers Scope of the workshop The main mathematical disciplines that have been used in computer science are discrete mathematics (especially, graph theory and ordered structures), logics (mostly proof theory for all kinds of logics, classical, intuitionistic, modal etc.) and category theory (cartesian closed categories, topoi etc.). General Topology has also been used for instance in denotational semantics, with relations to ordered structures in particular. Recently, ideas and notions from mainstream "geometric" topology and algebraic topology have entered the scene in Concurrency Theory and Distributed Systems Theory (some of them based on older ideas). They have been applied in particular to problems dealing with coordination of multi-processor and distributed systems (see the historical note ). Among those are techniques borrowed from algebraic and geometric topology: Simplicial techniques have led to new theoretical bounds for coordination problems. Higher dimensional automata have been modelled as cubical complexes with a partial order reflecting the time flows, and their homotopy properties allow to reason about a system's global behaviour. The first workshop on the subject Geometric and Topological Methods in Concurrency Theory has been held in Aalborg, Denmark, in June 1999. GETCO 2000 was organised as a workshop affiliated with CONCUR 2000 at Penn State University. The recent volumes 10 of Math. Struct. in Comp. Science and 39, issue 2, of Electr. Notes Theor. Comp. Science have been devoted to this area. The 3rd workshop in this series will be organised as a satellite to CONCUR 2001 at Aalborg University (Aug.21 - Aug.24). It aims at bringing together researchers from both the mathematical (geometry, topology, algebraic topology etc.) and computer scientific side (concurrency theorists, semanticians, researchers in distributed systems etc.) with an active interest in these or related developments. Topics include (but are not limited to) Semantics, Concurrency Theory, Model-checking, Abstract Interpretation, Fault-tolerant Protocols for Distributed Systems, Geometrical/Topological models, Applications of algebraic topology, Category theory etc. Paper submission The deadline for submission to the workshop is May 20, 2001 (midnight). Submissions may be of two forms: Short abstracts: up to 4 pages, in format A4, typeset 11 points Full papers: up to 12 pages, in format A4, typeset 11 points (excluding bibliography and technical appendices) Both forms of submission should include a separate page with the following informations: title, author(s), corresponding author, contact information and a 12-15 lines summary. Simultaneous submission to other conferences or journals is only allowed for short abstracts. Electronic submission is strongly encouraged. The paper or abstract should be sent by e-mail in the form of a postscript file to both the addresses raussen@math.auc.dk and goubault@aigle.saclay.cea.fr. The accompanying page should be sent in a separate email message. If surface mail has to be used, then 3 copies of the paper/abstract should be sent to: Martin Raussen, Dept. of Mathematical Sciences, Aalborg University, Fredrik Bajersvej 7G, DK-9220 Aalborg Ãst, Denmark. Publication Accepted papers will be made available in the BRICS Notes series. Electronic Notes in Theoretical Computer Science has kindly offered to publish the proceedings of the workshop - full papers only - in a special volume. The programme committee will decide upon necessary revisions and acceptance of papers to this volume after the workshop.
