=========================================== FIRST CALL FOR PAPERS Combined 28th International Workshop on Expressiveness in Concurrency and 18th Workshop on Structural Operational Semantics (EXPRESS/SOS 2021) http://icetcs.ru.is/express-sos2021/ Paris (France) August 23, 2021, Affiliated with CONCUR 2021 Submission deadline (full and short papers): Monday, June 21, 2021 =========================================== == INVITED SPEAKERS Amal Ahmed (Northeastern University, USA) Jan Friso Groote (Eindhoven University of Technology, The Netherlands) Dave Parker (University of Birmingham, UK) == 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 2021 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 - 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submission to journals, conferences or other workshops is only allowed for short papers; full papers must be unpublished.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=expresssos2021 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. We are monitoring the COVID-19 pandemic to decide if the workshop will take place physically in Paris, online or hybrid. Whatever the decision, we will guarantee the possibility of an online participation. == 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 2019 and EXPRESS/SOS 2020 is currently in progress. We will consider organising a special issue for EXPRESS/SOS 2021. == IMPORTANT DATES - Paper submission: June 21, 2021 - Notification date: July 26, 2021 - Camera ready version: August 9, 2021 - Workshop: August 23, 2020 == WORKSHOP CO-CHAIRS: Valentina Castiglioni (Reykjavik University, IS) Ornela Dardha (University of Glasgow, UK) == PROGRAM COMMITTEE: Ahmed Bouajjani (IRIF and University of Paris Diderot, France) Valentina Castiglioni (Reykjavik University, Iceland), co-chair Ornela Dardha (University of Glasgow, UK), co-chair Yuxin Deng (East China Normal University, China) David de Frutos-Escrig (Complutense Univeristy of Madird, Spain) Silvia Ghilezan (University of Novi Sad, Serbia) Paola Giannini (University of Piemonte Orientale, Italy) Karoliina Lehtinen (University of Liverpool, UK) Hernan Melgratti (University of Buenos Aires, Argentina) Valeria de Paiva (Samsung Research America, USA, and University of Birmingham, UK) Tatjana Petrov (University of Konstanz, Germany) Sabina Rossi (University Ca' Foscari Venice, Italy) Jurriaan Rot (Radboud University, The Netherlands) == CONTACT Prospective authors are encouraged to contact the co-chairs in case of questions at express-sos21@easychair.org
