============================================= CALL FOR PAPERS JOINT SYCO-STRING WORKSHOP 3rd Annual Workshop on String Diagrams in Computation, Logic, and Physics (STRING 2019) and the Fifth Symposium on Compositional Structures (SYCO 5) event: http://events.cs.bham.ac.uk/syco/strings3-syco5/ submit: https://easychair.org/conferences/?conf=strings3andsyco5 University of Birmingham, UK 4-6 September 2019 ============================================= STRING diagrams are a powerful tool for reasoning about processes and composition. Originally developed as a convenient notation for the arrows of monoidal and higher categories, they are increasingly used in the formal study of digital circuits, control theory, concurrency, quantum and classical computation, natural language processes, logic and more. String diagrams combine the advantages of formal syntax with intuitive aspects: the graphical nature of terms means that they often reflect the topology of systems under consideration. Moreover, diagrammatic reasoning transforms formal arguments into dynamic, moving images, thus building domain specific intuitions, valuable both for practitioners and pedagogy. The Symposium on Compositional Structures is a new interdisciplinary series of meetings aiming to support the growing community of researchers interested in the phenomenon of compositionality, from both applied and abstract perspectives, and in particular where category theory serves as a unifying common language. We welcome submissions from researchers across computer science, mathematics, physics, philosophy, and beyond, with the aim of fostering friendly discussion, disseminating new ideas, and spreading knowledge between fields. Submission is encouraged for both mature research and work in progress, and by both established academics and junior researchers, including students. Submission is easy, with no format requirements or page restrictions. The meeting does not have proceedings, so work can be submitted even if it has been submitted or published elsewhere. You could submit work-in-progress, or a recently completed paper, or even a PhD or Masters thesis. While no list of topics could be exhaustive, SYCO-STRING welcomes submissions with a compositional focus related to any of the following areas, in particular (but not necessarily) from the perspective of category theory: * logical methods in computer science, including classical and quantum programming, type theory, concurrency, natural language processing and machine learning; * graphical calculi, including string diagrams, Petri nets and reaction networks; * languages and frameworks, including process algebras, proof nets, type theory and game semantics; * abstract algebra and pure category theory, including monoidal category theory, higher category theory, operads, polygraphs, and relationships to homotopy theory; * quantum algebra, including quantum computation and representation theory; * tools and techniques, including rewriting, formal proofs and proof assistants, and game theory; * industrial applications, including case studies and real-world problem descriptions. Invited speakers ---------------- * Aleks Kissinger, Oxford * Jean Krivine, CNRS Paris * Koko Muroya, RIMS Kyoto * Detlef Plump, York * Mehrnoosh Sadrzadeh, QMU London * (more TBA) Important dates --------------- All deadlines are 23:59 anywhere-on-earth on the given dates. Submission deadline: 24 July 2019 Author notification: 7 August 2019 Travel support application deadline: To be announced Registration: To be announced Event dates: Wednesday 4 September to Friday 6 September 2019. SYCO will take place on Wednesday 4 September and the morning of Thursday 5 September. STRING will take place on the afternoon of Thursday 5 September and all day on Friday 6 September. Submissions ----------- Submission for both meetings will be by a single EasyChair page. There will be a single programme committee. Submission is now open: https://easychair.org/conferences/?conf=strings3andsyco5 Submissions should present research results in sufficient detail to allow them to be properly considered. We encourage the submission of work in progress, as well as mature results. There are no proceedings, so work can be submitted even if it has been previously published, or has been submitted for consideration elsewhere. There is no specific formatting requirement, and no page limit, although for long submissions authors should be aware that reviewers will not be able to read the entire document in detail. Think creatively—you could submit a recent paper, draft notes of a project in progress, or even a recent Masters or PhD thesis. To indicate the meeting for which you would like your submission to be considered, append "(STRING)" or "(SYCO)" in the title field of the EasyChair submission page. If you would be happy for it to be presented at either meeting, you may append both. If you have a submission which was deferred from a previous SYCO meeting, it will not automatically be considered for SYCO 5; you still need to submit it again explicitly. Such a submission will be prioritised for inclusion in the SYCO 5 programme. When submitting, append "(DEFERRED FROM SYCO X)" to the title of your paper, replacing "X" with the appropriate meeting number. There is no need to attach any documents.
