FIRST CALL FOR PAPERS
Combined
26th International Workshop on Expressiveness in Concurrency
and
16th Workshop on Structural Operational Semantics
(EXPRESS/SOS 2019)

https://express-sos2019.cs.ru.nl

Amsterdam (The Netherlands)
August 26, 2019, Affiliated with CONCUR 2019

Submission deadline (full and short papers):
Friday, June 21, 2019
===========================================

== SCOPE AND TOPICS
The EXPRESS/SOS workshop series aims at bringing together researchers
interested in the formal semantics of systems and programming
concepts, and in the expressiveness of computational models.

Topics of interest for EXPRESS/SOS 2019 include, but are not limited to:

- expressiveness and rigorous comparisons between models of
computation (process algebras, event structures, Petri nets, rewrite
systems)
- expressiveness and rigorous comparisons between programming
languages and models (distributed, component-based, object-oriented,
service-oriented);
- logics for concurrency (modal logics, probabilistic and stochastic
logics, temporal logics and resource logics);
- analysis techniques for concurrent systems;
- theory of structural operational semantics (meta-theory,
category-theoretic approaches, congruence results);
- comparisons between structural operational semantics and other
formal semantic approaches;
- applications and case studies of structural operational semantics;
- software tools that automate, or are based on, structural
operational semantics.

We especially welcome contributions bridging the gap between the above
topics and neighbouring areas, such as, for instance:
- computer security
- multi-agent systems
- programming languages and formal verification
- reversible computation
- knowledge representation

== SUBMISSION GUIDELINES:
We invite two types of submissions:
* Full papers (up to 15 pages, excluding references).
* Short papers (up to 5 pages, excluding references, not included in
the workshop proceedings)

All submissions should adhere to the EPTCS format (http://www.eptcs.org).
Simultaneous submission to journals, conferences or other workshops is
only allowed for short papers; full papers must be unpublished.

Submission is performed through EasyChair:
https://easychair.org/conferences/?conf=expresssos2019

The final versions of accepted full papers will be published in EPTCS.
It is understood that for each accepted submission one of the
co-authors will register to the workshop and give the talk.

== SPECIAL ISSUE
There is a long tradition of special issues of reputed international
journals devoted to the very best papers presented in prior editions
of the workshop.
For instance, a special issue of Information and Computation with
selected papers from EXPRESS/SOS 2018 is currently in progress.
We will consider organizing a special issue for EXPRESS/SOS 2019.
