Workshop on Computer Algebra Methods and Commutativity of Algebraic Diagrams (CAM-CAD) IRIT, Toulouse (France) 16-17 October 2009 *** CALL FOR PARTICIPATION *** *** AND *** *** DRAFT PROGRAM *** Categorical diagrams have multiple applications in mathematics (algebra, topology) and computer science (models and metamodels, rewriting systems, higher order languages). Diagrams (understood less strictly) can be found in physics, chemistry and other scientific domains. Many similar problems arise in computer-assisted treatment of diagrams in all these domains. In spite of the importance of diagrammatic methods, they are relatively little developed and underrepresented in the world of computer-assisted reasoning. This workshop aims to bring together researchers working on these subjects, to assess the current state of the art and identify open problems and future research directions. The main topics may be listed (non-exhaustively) as follows: algorithms that may be used in computer-assisted treatment of diagrams, treatment of diagrams in existing computer algebra systems, formal developments related to diagrams and category theory in proof-assistants, user interfaces and graphics for categorical diagrams. DRAFT PROGRAM Remark: the timetable is not fixed but actually (with talks already submitted) we plan to begin at 10:30 on Friday and end on Saturday at 12:30. 1. Lucas Dixon (Univ of Edinburgh) a) Graphical Reasoning in Compact Closed Categories for Quantum Computation b) Graphical Logic 2. Kosta Dosen (Math. Inst., Belgrade) Syntax for Split Preorders 3. Yves Guiraud (LORIA), Philippe Malbos (Lyon-1) Identities among relations for higher-dimensional rewriting systems 4. Robert Hein and François Lamarche (LORIA) Bifibrations and paths in categories. 5. Samuel Mimram (ENS-Lyon) A Unification Algorithm for Monoidal Theories 6. Zoran Petric (Math. Inst. Belgrade) Ordinals in Frobenius Monads 7. Damien Pous (INRIA Rhone-Alpes), Thomas Braibant (-"-) Algebraic tools for binary relations in Coq 8. Andre Rodin (ENS, Paris - rue d'Ulm) Diagrammatic syntax and its limits. 9. Pierre Rannou (Inst. Math. de Luminy) Diagram rewriting and applications 10. A. El Khoury, S. Soloviev (IRIT) Title to be presented. Papers presented at the workshop will be published on the web site of the workshop and are planned to be selected for submission, in complete and revised form, to a special issue of an international journal. IMPORTANT UPDATE We will ask for a modest participation fee (30 euros to be used for 3-4 coffee breaks and a lunch on Friday at the university restaurant). We plan to organize an "informal" dinner on Friday evening. IMPORTANT DATES: Submission deadline: we expect a full paper or an extended abstract by 30 September 2009. As an exception, we may still consider to extend the list of talks if the full paper or extended abstract will come (for sure) by 30 september, and we will be notified before 10 september - as usual, the message should contain the title and a short abstract.
