The 4th International Conference on Applied Category Theory will take place at the Computer Laboratory of the University of Cambridge on 12-16 July 2021, preceded by the Adjoint School 2021 on 5-9 July. This conference follows previous events at MIT, Oxford and Leiden.
The conference will be a hybrid event, with physical attendees present in Cambridge, and other participants taking part online. Due to the need for physical distancing, the number of in-person registrations will be limited, so please don't book your travel or accommodation until your registration is confirmed.
Applied category theory is a topic of interest for a growing community of researchers, interested in studying many different kinds of systems using category-theoretic tools. These systems are found across computer science, mathematics, and physics, as well as in social science, linguistics, cognition, and neuroscience. The background and experience of our members is as varied as the systems being studied. The goal of Applied Category Theory is to bring researchers in the field together, disseminate the latest results, and facilitate further development of the field.
We accept contributions across the pure-applied spectrum, from pure mathematical research, to case studies describing successful application of category-theoretic tools in industry. However, submissions at the most mathematical end should take care to explain how this work could be applied to a subject outside of pure category theory itself, while submissions at the most applied end should contain a clear explanation of the category theory involved.
To accommodate the publishing conventions of different fields, we accept submissions of both original research papers, and also work accepted/submitted/published elsewhere. Accepted original research papers will be invited for publication in a proceedings volume. The keynote addresses will be drawn from the best accepted papers. The conference will include an industry showcase event.
Some financial support is available to support attendance by junior researchers who would like to attend the conference in person. To apply for this, send an email to Lukas Heidemann at firstname.lastname@example.org from an academic email address, with subject line "ACT 2021 Financial Support Application".
In your email, please give the following information: your name and affiliation; an estimate of the total cost for you to attend; the amount you are requesting; whether or not you have submitted a paper (and if so, its submission number); whether you have secured or applied for partial funding from another source. Also, please give a brief statement about why you believe that COVID restrictions will not prevent you from attending (e.g. "I live in the UK, and current government projections indicate no restrictions on conference travel and participation in July.")
You will be informed about the result of your application on Tuesday 8 June. Successful applicants for financial support will be able to register for free during the Priority Registration period, which opens on Wednesday 9 June.
All participants, both physical and online, must be registered. Registration for online participation will open soon.
Priority registration for physical participants will open on Wednesday 9 June. In this priority period, registration is restricted to speakers, sponsors, and those who have been awarded financial support. Ordinary physical registration opens on Monday 13 June. The total number of physical registrations will be restricted to allow for social distancing during the conference.
Current UK government projections indicate that physical conference participation will be allowed for the conference dates. However, there of course remains a possibility that circumstances may change, and the organizers may reluctantly decide to cancel the physical confence due to circumstances related to the pandemic. If the physical conference is cancelled, any money paid for official conference accommodation or registration would be refunded. However, the organizers will not be liable for any other costs that physical participants may have, such as travel costs.
The conference will take place physically at the Department of Computer Science at the University of Cambridge. Information about travel will follow soon.
Official conference accommodation will be available for priority booking by physical participants at a College of the university. The deadline for booking this official accommodation is Monday 13 June. The booking code will only be made available to those who have registered as a physical participant. The number of available accommodation rooms matches the number of registration slots, so if you have successfully registered for physical participation, you are guaranteed to be able to book accommodation, as long as you do so before the deadline. In the unfortunate event that the physical conference is cancelled due to COVID, the cost of this physical accommodation will be fully refunded.
The physical conference will be organized in a COVID-safe way. In particular, participants will be expected to observe social distancing, the number of participants will be restricted, seating in the lecture theatre will be well-spaced, coffee and lunch breaks will be outdoors where possible, and masks will be required while not eating or drinking.
Submission will be via EasyChair: https://easychair.org/conferences/?conf=act20210
Two types of submissions are accepted, both of which will be reviewed using the same standards:
Papers in the two tracks will be reviewed against the same standards of quality. Since ACT is an interdisciplinary conference, we use two tracks to accommodate the publishing conventions of different disciplines. For example, those from a Computer Science background may prefer the Proceedings Track, while those from a Mathematics, Physics or other background may prefer the Non-Proceedings Track. However, authors from any background are free to choose the track that they prefer, and submissions may be moved from the Proceedings Track to the Non-Proceedings Track at any time at the request of the authors.
Contributions must be submitted in PDF format. Submissions to the Proceedings Track must be prepared with LaTeX, using the EPTCS style files available at http://style.eptcs.org.
The Adjoint School is an annual collaborative research event, in which junior researchers work on cutting-edge topics in applied category theory, guided by expert mentors. Traditionally, after a four month reading course, the participants meet at the venue of the ACT conference for a week of in-person research collaborator. Due to the pandemic, this year the research week will be held online. The students will share the results of their research in a special session during the ACT conference.
