Second Symposium on Compositional Structures (SYCO 2)

University of Strathclyde
17-18 December, 2018

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 welcomes submissions with a compositional focus related to any of the following areas, in particular from the perspective of category theory:

This new series aims to bring together the communities behind many previous successful events which have taken place over the last decade, including Categories, Logic and Physics, Categories, Logic and Physics (Scotland), Higher-Dimensional Rewriting and Applications, String Diagrams in Computational, Logic and Physics, Applied Category Theory, Simons Workshop on Compositionality, the Yorkshire and Midlands Category Theory Seminar, and the Peripatetic Seminar in Sheaves and Logic.

SYCO 1 was held in September 2018 at the University of Birmingham. The steering committee hopes that SYCO will become a regular fixture in the academic calendar, running regularly throughout the year, and becoming over time a recognized venue for presentation and discussion of results in an informal and friendly atmosphere.

The intention is for SYCO to be a community meeting, where people have enough time to explain their ideas, and without an unnecessarily competitive atmosphere. To encourage this, in the event that more submissions are received of an acceptable standard than can be accommodated in the timetable, the programme committee may choose to defer some submissions to a future meeting, rather than reject them. This would be done based largely on submission order, giving an incentive for early submission, but would also take into account other requirements, such as ensuring a broad scientific programme. Deferred submissions can then be re-submitted to any future SYCO meeting, where they will be prioritised for inclusion in the programme, and where they will not need to be re-reviewed. Meetings will be held sufficiently frequently to avoid a backlog of deferred papers.


Submission is currently open. Please visit EasyChair to make your submission.

Submissions should present research results in sufficient detail to allow them to be properly considered by members of the programme committee, who will assess their interest to the SYCO community. 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 may not be able to read the entire document in detail. Think creatively—you could submit a recent paper, or a draft notes of a project in progress, or even a recent Masters or PhD thesis.

If you made a submission to SYCO 1 which was deferred, it will not automatically be considered for SYCO 2; you still need to submit it again through EasyChair. Such a submission will be prioritised for inclusion in the SYCO 2 programme. When submitting, enter the author and title information as usual into the EasyChair submission form, but in the "abstract" field, just state that it is a deferred submission and give the SYCO 1 submission number. There is no need to attach any documents, but you can if you like, for example if the work has developed since the previous submission; in this case, please give a one-sentence summary in the "Abstract" field of the EasyChair submission form of the way it has changed.
