This volume contains the proceedings of the 17th international workshop on Expressiveness in Concurrency (EXPRESS'10) which took place on August 30th, 2010 in Paris. As in previous years, the workshop was co-located with CONCUR'10.
The EXPRESS workshops aim at bringing together researchers interested in the relations between various formal systems, particularly in the field of Concurrency. Their focus has traditionally been on the comparison between programming concepts (such as concurrent, functional, imperative, logic and object-oriented programming) and between mathematical models of computation (such as process algebras, Petri nets, event structures, modal logics, and rewrite systems) on the basis of their relative expressive power. The EXPRESS workshop series has run successfully since 1994 and over the years this focus has become broadly construed. We are now aiming to bring together researchers who are interested in the expressiveness and comparison of formal models that broadly relate to concurrency. In particular, this includes emergent computational paradigms such as quantum computing, biocomputing, logic and interaction, game-theoretic models, and service-oriented computing.
In response to this year's call for papers, we received twenty paper submissions. The programme committee selected ten papers for presentation at the workshop. These proceedings contain these selected contributions. The workshop also had two invited presentations, one by Daniele Varacca on Causality in the pi-calculus and the other one, joint with the SOS workshop, by Catuscia Palamidessi on Compositionality of Secure Information Flow.
We would like to thank the authors of the submitted papers, the invited speakers, the members of the programme committee, and their subreviewers for their contribution to both the meeting and this volume. We also thank the CONCUR organizing committee for hosting EXPRESS'10. We are grateful to Luis Pino for helping us with the edition of the pre-proceedings distributed at the workshop. Finally, we would like to thank our EPTCS editor Rob van Glabbeek for publishing these proceedings and his help during the preparation.
