Preliminary Announcement --- FLoC'06 The 2006 Federated Logic Conference Seattle, Washington, USA August 10 -- August 22, 2006 http://research.microsoft.com/projects/FLoC2006/home.html http://research.microsoft.com/floc06/ In 1996, as part of its Special Year on Logic and Algorithms, DIMACS hosted the first Federated Logic Conference (FLoC). It was modeled after the successful Federated Computer Research Conference (FCRC), and synergetically brought together conferences that apply logic to computer science. The second Federated Logic Conference (FLoC'99) was held in Trento, Italy, in 1999, and the third (FLoC'02) was held in Copenhagen, Denmark, in 2002. We are pleased to announce the fourth Federated Logic Conference (FLoC'06) to be held in Seattle, Washington, in August 2006, at the Seattle Sheraton (http://www.sheraton.com/seattle) The following conferences will participate in FLoC. Int'l Conference on Computer-Aided Verification (CAV) Int'l Conference on Rewriting Techniques and Applications (RTA) IEEE Symposium on Logic in Computer Science (LICS) Int'l Conference on Logic Programming (ICLP) Int'l Conference on Theory and Applications of Satisfiability Testing (SAT) Int'l Joint Conference on Automated Reasoning (IJCAR) Pre-conference workshops will be held on August 10-11. LICS, RTA, and SAT will be held in parallel on August 12-15, to be followed by mid-conference workshops and excursions on August 15-16. CAV, ICLP, and IJCAR will be held in parallel on August 16-21, to be followed by post-conference workshops on August 21-22. Plenary events involving all the conferences are planned. Calls for papers and call for workshop proposals will be issued in the near future. For additional information regarding the participating meetings, please check the FLoC web page (see above) later this summer. FLoC'06 Steering Committee Moshe Y.

Preprint: Modelling fundamental 2-categories for directed homotopy
by Marco Grandis 23 Mar '05

23 Mar '05

The following preprint is available. It is a sequel of my previous work on the fundamental category of a directed space, announced on this list in May 2004. M. Grandis Modelling fundamental 2-categories for directed homotopy Dip. Mat. Univ. Genova, Preprint 527 (2005), 34 p. Abstract. Directed Algebraic Topology is a recent field, deeply linked with ordinary and higher dimensional Category Theory. A 'directed space', e.g. an ordered topological space, has directed homotopies (generally non reversible) and fundamental n-categories (replacing the fundamental n-groupoids of the classical case). Finding a simple model of the latter is a non-trivial problem, whose solution gives relevant information on the given 'space'; a problem which is also of interest in general Category Theory, as it requires equivalence relations wider than categorical equivalence. Taking on a previous work on "The shape of a category up to directed homotopy", we study now the fundamental 2-category of a directed space. All the notions of 2-category theory used here are explicitly reviewed. http://www.dima.unige.it/~grandis/Shp2.pdf http://www.dima.unige.it/~grandis/Shp2.ps ________________ The first paper, "The shape of a category up to directed homotopy", can also be downloaded: Abstract: http://www.dima.unige.it/~grandis/Shp.Abs.html Paper: http://www.dima.unige.it/~grandis/Shp.pdf http://www.dima.unige.it/~grandis/Shp.ps ________________ Marco Grandis Dipartimento di Matematica Universita` di Genova via Dodecaneso 35 16146 GENOVA, Italy e-mail: grandis(a)dima.unige.it tel: +39.010.353 6805 fax: +39.010.353 6752 http://www.dima.unige.it/~grandis/ 24-Mar-2005 13:53:44 -0400,6340;000000000001-00000000

First CfP: GETCO 2005
by Uli Fahrenberg 23 Mar '05

23 Mar '05

Seventh workshop on Geometric and Topological Methods in Concurrency GETCO 2005 Affiliated with CONCUR 2005 Venue: San Francisco, California Conference dates: CONCUR: 23-26 August 2005 GETCO: 21 August 2005 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 modeled 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 or PDF file to both the addresses uli(a)math.aau.dk and Haucourt(a)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 1 June 2005. Important Dates * Deadline for submission: 1 June 2005 * Notification of acceptance: 7 July 2005 * Final version (for the preproceedings): 27 July 2005 * CONCUR: 23-26 August 2005 * GETCO: 27 August 2005 Publication We expect that as in the years before, the preliminary proceedings of the workshop will published in the BRICS Notes series, and the proceedings with Electronic Notes in Theoretical Computer Science.
