[TYPES/announce] SYCO 6 Final Call for Participation

[Daniel Marsden]

SIXTH SYMPOSIUM ON COMPOSITIONAL STRUCTURES (SYCO 6)
-- including a Category Theory PhD Recruitment Fair --

University of Leicester, UK
   16-17 December, 2019

 http://events.cs.bham.ac.uk/syco/6/

The Symposium on Compositional Structures (SYCO) is an
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.
Previous SYCO events have been held at University of Birmingham,
University of Strathclyde, University of Oxford, and Chapman University.

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. Think creatively---
you could submit a recent paper, or notes on work in progress, or even
a recent Masters or PhD 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:

- 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.

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 Computation, Logic and Physics",
"Applied Category Theory", "Simons Workshop on Compositionality", and
the "Peripatetic Seminar in Sheaves and Logic".

SYCO is 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. To help create this community, and to avoid the
need to make difficult choices between strong submissions, in the
event that more good-quality submissions are received 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 be re-submitted to any future SYCO meeting, where they
would not need peer review, and where they would be prioritised for
inclusion in the programme. This will allow us to ensure that speakers
have enough time to present their ideas, without creating an
unnecessarily competitive reviewing process. Meetings will be held
sufficiently frequently to avoid a backlog of deferred papers.

# INVITED SPEAKERS

Gabriella Bohm, Wigner Research Centre for Physics
Jennifer Hackett, University of Nottingham

# PhD RECRUITMENT FAIR

This event will include a poster session advertising PhD opportunities
in category theory and related disciplines. If you are interested in
advertising PhD opportunities at your institution, please email Simona
Paoli at <sp424 at leicester.ac.uk>. We expect significant participation
from Masters students and final-year undergraduates who are
considering further study in this area.
