Abstract

INFINITY 2002, the 4th International Workshop on Verification of Infinite-State Systems, was held as a satellite workshop of CONCUR 2002 (the 13th International Conference on Concurrency Theory) in Brno, Czech Republic, on August 24, 2002. The aim of the workshop is to provide a forum for researchers interested in the development of mathematical techniques for the analysis and verification of systems with infinitely many states. The topics of INFINITY 2002 included the following: techniques for modeling and analysis of infinite-state systems, equivalence-checking and model-checking with infinite-state systems, parameterized systems, calculi for mobility and security, finite-state abstractions of infinite-state systems.The volume consists of six contributed papers selected by the INFINITY 2002 programme committee. The papers were reviewed by the program committee consisting, besides editors, of Parosh Abdulla(Uppsala (SE))Julian Bradfield(Edinburgh (UK))Didier Caucal(Irisa (F))Hubert Comon(LSV Cachan (F))Giorgio Delzanno(Genova (I))Yoram Hirshfeld(Tel-Aviv (Israel))Denis Lugiez(Marseille (F))Bernhard Steffen(Dortmund (D))P.S. Thiagarajan(Chennai (India))Moshe Vardi(Rice (USA))The programme of INFINITY 2002 was further enriched by an invited talk given by Colin Stirling, and by four short presentations of work in progress.This volume will be published as volume 68(6) in the series Electronic Notes in Theoretical Computer Science (ENTCS). This series is published electronically through the facilities of Elsevier Science B.V. and its auspices.
