Scope (NEW!!)

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. This year we wish to make this development "official" and further widen the scope of EXPRESS. We are aiming to bring together researchers who are interested in the expressiveness and comparison of formal models that broadly relate to concurrency. In particular, we wish to include emergent computational paradigms such as quantum computing, biocomputing, logic and interaction, game-theoretic models, and service-oriented computing.

Invited Speakers

Samson Abramsky, Oxford (UK)

Call for Papers

The submission site is closed!

Paper submission is performed through the EXPRESS '09 EASY CHAIR SERVER and it goes in two steps: abstract submission and paper submission. Submissions may be of two forms:

Simultaneous submission to other conferences or journals is only allowed for short papers. The submissions must already use the EPTCS-style format. A preliminary version of the proceedings will be available at the workshop. After the workshop, authors of full papers will be asked to prepare a final version of their paper to be published in the EPTCS (Electronic Proceedings in Theoretical Computer Science). It is recommended that the final version of the paper includes as much as possible proofs and technical material.

Special issue: The very best papers will be invited in a special issue of the journal of Mathematical Structures in Computer Science; such papers will then be peer-reviewed and selected according to the standard journal policy. However, differently from a regular journal submission, papers will be handled quickly and the special issue should appear during 2010.

Important Dates

Abstract submission: June 7th, 2009 (extended!!)
Paper submission: June 14th, 2009 (extended!!)
Notification date: July 18th, 2009
Submission of preliminary version for the Proceedings: July 23rd, 2009
Submission of final version for EPTCS: September 27th, 2009

The EXPRESS workshops were originally held as meetings of the HCM project EXPRESS, which was active with the same focus from January 1994 till December 1997. The first three workshops were held respectively in Amsterdam (1994, chaired by Frits Vaandrager), Tarquinia (1995, chaired by Rocco De Nicola), and Dagstuhl (1996, co-chaired by Ursula Goltz and Rocco De Nicola). EXPRESS'97, which took place in Santa Margherita Ligure and was co-chaired by Catuscia Palamidessi and Joachim Parrow, was organized as a conference with a call for papers and a significant attendance from outside the project. EXPRESS'98 was held as a satellite workshop of the CONCUR'98 conference in Nice, co-chaired by Ilaria Castellani and Catuscia Palamidessi, and like on that occasion EXPRESS'99 was hosted by the CONCUR'99 conference in Eindhoven, co-chaired by Ilaria Castellani and Björn Victor. The EXPRESS'00 workshop was held as a satellite workshop of CONCUR 2000, Pennsylvania State University, co-chaired by Luca Aceto and Björn Victor. The EXPRESS'01 workshop was held at Aalborg University as a satellite of CONCUR'01 and was co-chaired by Luca Aceto and Prakash Panangaden. The EXPRESS'02 workshop was held at Brno University as a satellite of CONCUR'02 and was co-chaired by Uwe Nestmann and Prakash Panangaden. The EXPRESS'03 workshop was co-located with CONCUR 2003 in Marseille and was co-chaired by Flavio Corradini and Uwe Nestmann. The EXPRESS '04 workshop was co-located with CONCUR 2004 in London and was co-chaired by Jos Baeten and Flavio Corradini. The EXPRESS '05 workshop was co-located with CONCUR 2005 in San Francisco and was co-chaired by Jos Baeten and Iain Phillips. The EXPRESS '06 workshop was co-located with CONCUR 2006 in Bonn and was co-chaired by Roberto Amadio and Iain Phillips. The EXPRESS '07 workshop was co-located with CONCUR 2007 in Lisbon and was co-chaired by Roberto Amadio and Thomas Hildebrandt. The EXPRESS '08 workshop was co-located with CONCUR 2008 in Toronto and was co-chaired by Daniele Gorla and Thomas Hildebrandt.
