Apologies for multiple copies of this email; please distribute as you see fit. 22st International Conference on Relational and Algebraic Methods in Computer Science RAMiCS 2026 Institute of Mathematics of the Polish Academy of Sciences Będlewo, Poland, 7-10 April 2026 https://ramics-conf.github.io/2026 Additionally to the standard Call for Papers, RAMiCS is also calling for presentations or short contributions. 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, or any other format. A presentation may also be a tutorial, or an open question of interest to the community. These presentations will *not* be published in the conference proceedings. IMPORTANT DATES: Submission: 26 February 2026 Notification: 3 March 2026 RAMiCS registration: 7 March 2026 INVITED SPEAKERS: * Lorenzo Clemente, University of Warsaw, Poland * Anupam Das, University of Birmingham, United Kingdom * Jana Wagemaker, Radboud University, Nijmegen, The Netherlands 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 presentations 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 ramics2026@easychair.org by 26 February 2026.
