(Apologies for multiple posting) CALL FOR SHORT CONTRIBUTIONS / POSTERS 20th International Conference on Relational and Algebraic Methods in Computer Science RAMiCS 2023 3 to 6 April 2023, Technologiezentrum Augsburg, Germany https://ramics20.lis-lab.fr/ Additionally to the standard CfP, RAMiCS is also calling for short contributions and posters. We are hence calling for presentations of original, unfinished, already published, or otherwise interesting work within the topics of the RAMiCS conferences. The submission can be in the form of a poster, an abstract, a paper submitted to or published at another conference, etc. Short contributions will *not* be published in the conference proceedings. IMPORTANT DATES: Submission: January 27, 2023 Notification: February 03, 2023 RAMiCS 2023: April 03-06, 2023 INVITED SPEAKERS: Alexander Knapp, Augsburg University, Germany John Stell, University of Leeds, UK Valeria Vignudelli, CNRS/ENS Lyon, France GENERAL INFORMATION: Since 1994, the RAMICS conference series has been the main venue for research on relation algebras, Kleene algebras and similar algebraic formalisms, and their applications as conceptual and methodological tools in computer science and beyond. TOPICS: We invite short submissions in the general fields of algebras relevant to computer science and applications of such algebras. Topics include but are not limited to: * Theory - algebras such as semigroups, residuated lattices, semirings, Kleene algebras, relation algebras and quantales - their connections with program logics and other logics - their use in the theories of automata, concurrency, formal languages, games, networks and programming languages - the development of algebraic, algorithmic, category-theoretic, coalgebraic and proof-theoretic methods for these theories - their formalisation with theorem provers * Applications - tools and techniques for program correctness, specification and verification - quantitative and qualitative models and semantics of computing systems and processes - algorithm design, automated reasoning, network protocol analysis, social choice, optimisation and control - industrial applications SUBMISSION INSTRUCTIONS: Please send your short submission as a single pdf file to ramics2023@easychair.org<mailto:ramics2023@easychair.org> by January 27, 2023.
