This year the CONCUR conference was in its 20th edition, and to celebrate 20 years of CONCUR, the conference program included a special session organized by the IFIP Working Groups 1.8 “Concurrency Theory” and 2.2 “Formal De- scriptionofProgrammingConcepts”aswellasaninvitedlecturegivenbyRobin Milner, one of the fathers of the concurrency theory researcharea. This edition of the conference attracted 129 submissions. We wish to thank all their authors for their interest in CONCUR 2009. After careful discussions, the Program Committee selected 37 papers for presentation at the conference. Eachof them wasaccurately refereedby atleastthree reviewers(four reviewers for papers co-authored by members of the Program Committee), who delivered detailedandinsightfulcommentsandsuggestions.TheconferenceChairswarmly thank all the members of the ProgramCommittee and all their sub-referees for the excellent support they gave, as well as for the friendly and constructive discussions. We would also like to thank the authors for having revised their papers to address the comments and suggestions by the referees. The conference program was enriched by the outstanding invited talks by Martin Abadi, Christel Baier, Corrado Priami and, as mentioned above, Robin Milner. The conference this year was jointly organized with the 7th International ConferenceonComputationalMethodsinSystemsBiology(CMSB2009)andthe 6thInternationalWorkshoponWebServiceandFormalMethods(WS-FM2009) emphasizing, on the one hand, the close connections and similarities between concurrent, artificial systems, and biological, natural systems and, on the other hand, the current pervasiveness of concurrent, distributed and mobile comput- ing technologies. The invited talk by Corrado Priami, held in conjunction with CMSB, and the one by Robin Milner, held in conjunction with WS-FM, were a witness of the commonalities of interests of these conferences and of the corre- sponding researchcommunities. As additional co-located events, CONCUR2009 included the following satellite workshops: 16th International Workshop on Ex- pressiveness in Concurrency (EXPRESS), Second Interaction and Concurrency Experience (ICE), 11th International Workshop on Verification of Infinite-State Systems (INFINITY), Third Workshop on Membrane Computing and Biologi- cally Inspired Process Calculi (MeCBIC), 7th International Workshop on Secu- rity Issues in Concurrency (SecCo), 6th Workshop on Structural Operational Semantics (SOS) and Young Researchers Workshop on Concurrency Theory (YR-CONCUR). VI Preface We would like to thank all the people who contributed to the organization of CONCUR 2009, and the generous support from the Alma Mater Studiorum – Universita` degli Studi di Bologna and from Microsoft Research Cambridge. We are also grateful to Andrei Voronkov, who allowed us to use the wonderful free conference software system EasyChair, which we used for the electronic submission of papers, the refereeing process and the ProgramCommittee work.
