CALL FOR PAPERS RAMiCS 2026 21st International Conference on Relational and Algebraic Methods in Computer Science Institute of Mathematics of the Polish Academy of Sciences Będlewo, Poland, 7-10 April 2026 https://ramics-conf.github.io/2026 The RAMiCS conference series is the main venue for research on relational algebras, Kleene algebras and similar algebraic formalisms, and their applications as conceptual and methodological tools in computer science and beyond. RAMiCS 2026 will be organized at the Research and Conference Center of the Institute of Mathematics of the Polish Academy of Sciences in Będlewo, close to Poznań in Poland, and will feature both a classical conference and interactive sessions.

Theoretical aspects include semigroups, residuated lattices, semirings, Kleene algebras, relation algebras, quantales and other algebras; 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 of these formalisms span a wide range of domains, including tools and techniques for program specification, verification, and correctness; qualitative and quantitative models of computing systems; algorithm design; automated reasoning; network protocol analysis; optimisation; control; and even social choice theory. We are calling for submission of original work not published or under review for publication elsewhere. The proceedings will be published as part of Springer LNCS. As for earlier RAMiCS conferences, we intend to publish a journal special issue with revised and extended versions of a selection of the best papers. Submission is via EasyChair at https://easychair.org/conferences/?conf=ramics2026 For more information, see https://ramics-conf.github.io/2026/ Please feel free to forward this announcement to interested colleagues.
