[Apologies if you should receive multiple copies of this:] Sixth workshop on Geometric and Topological Methods in Concurrency and Distributed Computing GETCO 2004 Affiliated with DISC 2004 Venue: Amsterdam, the Netherlands Conference dates: DISC: 4-8 October 2004 GETCO: 4 October 2004 Call for Papers Scope 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 GETCO workshops aim at bringing together researchers from both the mathematical (geometry, topology, algebraic topology etc.) and computer scientific side (concurrency theorists, semanticians, algorithmicians, researchers in distributed systems etc.) with an active interest in these or related developments. Topics include (but are not limited to): * Algorithmics for Concurrent or Distributed Systems * Fault-tolerant Protocols for Distributed Systems * Semantics * Concurrency Theory * Model-checking * Abstract Interpretation * Geometric/Topological models * Applications of algebraic topology * Category theory Paper submission Submissions to the workshop 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 information: 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.aau.dk and haucourt@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: Emmanuel Haucourt, DTSI/SLA, bat. 528, CEA Saclay, 91191 Gif-sur-Yvette, France. The deadline for submissions is 28 June 2004. Important Dates * Deadline for submission: 28 June 2004 * Notification of acceptance: 2 August 2004 * Final version (for the preproceedings): 23 August 2004 * DISC: 4-8 October 2004 * GETCO: 4 October 2004 Publication Contacts have been taken so that accepted papers will be made available in the BRICS Notes series. Contacts have been taken with Electronic Notes in Theoretical Computer Science 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.
