SYCO 3 - Call for Papers
by JS Lemay 29 Jan '19

29 Jan '19

THIRD SYMPOSIUM ON COMPOSITIONAL STRUCTURES (SYCO 3) University of Oxford 27-28 March, 2019 http://events.cs.bham.ac.uk/syco/3/ <http://events.cs.bham.ac.uk/syco/3/> 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. The first SYCO was in September 2018 at the University of Birmingham. The second SYCO was in December 2019, at the University of Strathclyde, each attracting about 70 people. 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 will be 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 Marie Kerjean, INRIA Bretagne Atlantique Alessandra Palmigiano, Delft University of Technology and University of Johannesburg # IMPORTANT DATES All times are anywhere-on-earth. - Submission deadline: Friday 15 February 2019 - Author notification: Wednesday 27 February 2019 - Registration deadline: Wednesday 20 March 2019 - Symposium dates: Wednesday 27 and Thursday 28 March 2019 # SUBMISSIONS Submission is by EasyChair, via the following link: - https://easychair.org/conferences/?conf=syco3 <https://easychair.org/conferences/?conf=syco3> Submissions should present research results in sufficient detail to allow them to be properly considered by members of the programme committee, who will assess papers with regards to significance, clarity, correctness, and scope. 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 understand that reviewers may not be able to read the entire document in detail. # FINANCIAL SUPPORT Some funding is available to cover travel and subsistence costs, with a priority for PhD students and junior researchers. To apply for this funding, please contact the local organizers Antonin Delpeuch (antonin.delpeuch(a)cs.ox.ac.uk <mailto:antonin.delpeuch@cs.ox.ac.uk>) or Ben Musto (benjamin.musto(a)cs.ox.ac.uk <mailto:benjamin.musto@cs.ox.ac.uk>) with subject line "SYCO 3 funding request" by March 6, with a short statement of your current status, travel costs and funding required. # PROGRAMME COMMITTEE Fatimah Ahmadi, University of Oxford Corina Cirstea, University of Southampton Bob Coecke, University of Oxford Carmen Maria Constantin, University of Oxford Antonin Delpeuch, University of Oxford Brendan Fong, Massachusetts Institute of Technology Dan Ghica, University of Birmingham Giuseppe Greco, Utrecht University Helle Hvid Hansen, Delft University Jules Hedges, University of Oxford Chris Heunen, University of Edinburgh Dominic Horsman, University of Grenoble Dimitri Kartsaklis, Apple Aleks Kissinger, Radboud University Nijmegen Alexander Kurz, Chapman University Jean-Simon Lemay, University of Oxford Martha Lewis, University of Amsterdam Dan Marsden, University of Oxford Samuel Mimram, École Polytechnique Nina Otter, UCLA Simona Paoli, University of Leicester Robin Piedeleu, University of Oxford David Reutter, University of Oxford Christine Tasson, Paris Diderot University Jamie Vicary, University of Birmingham Tamara von Glehn, University of Cambridge Quanlong Wang, University of Oxford Gijs Wijnholds, Queen Mary University of London Philipp Zahn, University of St.Gallen [For admin and other information see: http://www.mta.ca/~cat-dist/ ]

Research associate in computational effects modelling and axiomatics
by Ohad Kammar 17 Jan '19

17 Jan '19

Hi, I'm looking for a postdoc, and can currently offer a position until January 2021 (inclusive). You'll be joining me at the Laboratory for the Foundations of Computer Science (LCFS) at the School of Informatics in the University of Edinburgh. We'll be looking at the semantic foundations of computational effects and the foundations of statistical probabilistic programming. More details here, with a brief summary below: https://www.vacancies.ed.ac.uk/pls/corehrrecruit/erq_jobspec_version_4.jobs… I'm at POPL this week --- in case you're here and want to chat. Otherwise, just email me. If you're not currently looking for a postdoc position, but know someone who is, please forward this information to them. Yours, Ohad. --------------------------------------------------------- Closing date: Friday 15th February 2019 at 5pm (GMT) Interviews (expected): 27 or 28 February 2019 Project Information Programs exhibit implicit behaviour, such as I/O and state interaction, probabilistic non-determinism, Bayesian conditioning, and gradient manipulation, under the umbrella term 'computational effects'. Computational effects pose challenges in modelling and reasoning about programs, as their interaction with other programming language theories, such as higher-order structure and polymorphism, is still poorly understood. Axiomatics is a highly successful technique in reasoning about computational effects. In this project, you will conduct basic research into the connections between axiomatics and denotational modelling of computational effects. You will also specialise this theory towards the foundations of probabilistic programming. Essential criteria * Completed, or near completion of, a PhD in computer science or mathematics, or equivalent experience. * Demonstrable experience in denotational modelling of programming languages. * Demonstrable working knowledge in category theory. * Demonstrable working knowledge in domain theory. * Ability to communicate clearly complex technical material orally and in writing. Desirable criteria * Experience with axiomatic verification of higher-order programs with effects. * Demonstrable working knowledge in refinement type systems and their mathematical models. * Demonstrable working knowledge in measure theory, probability, and statistics. * Demonstrable experience in programming with and/or modelling effect handlers. * Demonstrable experience in programming in and/or modelling statistical probabilistic programming languages * Experience in publication and presentation in international programming language venues. * Demonstrable knowledge in designing and solving recursive domain equations.
