----------------------------------------------------------------------------------------- GENERAL CALL FOR PAPERS: Proceeding for Workshop D1 ----------------------------------------------------------------------------------------- During May 01 - May 06, Workshop D1 "Groebner Bases in Cryptography, Coding Theory, and Algebraic Combinatorics" was held, within the framework of the Special Semester on Groebner Bases at RICAM and RISC, Linz-Austria (see www.ricam.oeaw.ac.at/srs/groeb/). The workshop was divided into three consecutive sessions: Coding (chaired by M. Sala), Cryptography (chaired by L. Perret) and Algebraic Combinatorics (chaired by M. Klin), and started with an introductory lecture on Groebner bases by Bruno Buchberger himself. The conference included tutorials/surveys, research talks and poster presentations. The audience consisted of more than 120 researchers arrived from all over the world. The proceeding for the conference will be published through three different media: 1) a volume of the RISC Book Series, covering the Algebraic Combinatoric contributions; 2) a special issue of Journal of Symbolic Computation, covering research results for the Coding and Crypto parts whose authors plan to publish as full journal papers (Managing Editor: L. Perret); 3) a volume of the RISC Book Series, including any contribution from the Coding and Crypto sessions, either in a short-note version or in a long-paper version (Managing Editor: M. Sala). Separate open calls for 1), 2) and 3) will appear soon. All of them will accept also contributions by experts that have not attended the workshop, however there will be scope restrictions which will be clarified in any call.
