Applied Category Theory 2020 (Part 2)

Due to the coronavirus outbreak, many universities are moving activities online. This is a great opportunity to open up ACT2020 to a broader audience, with speakers from around the world.

The conference will take place July 6-10 online, coordinated by organizers in Boston USA. Each day there will be around six hours of live talks, which will be a bit more spaced out than usual to accommodate the different time zones of our speakers. All the talks will be both live streamed and recorded on YouTube. We will also have chat rooms and video chats in which participants can discuss various themes in applied category theory.

We will give more details as they become available and post updates on our official webpage:

Since there is no need to book travel, we were able to postpone the acceptance notification, and hence the submission deadline. If you would like to speak, please prepare an abstract or a conference paper according to the instructions here:

Important dates (all in 2020)

• Submission of contributed papers: May 10
• Acceptance/Rejection notification: June 7
• Tutorial day: July 5
• Main conference: July 6-10

Registration will now be free; please register for the conference ahead of time here:

We will send registering participants links to the live stream, the recordings, and the chat rooms, and we’ll use the list to inform participants of any changes.


To give a talk at ACT2020, you have to submit a paper. You can submit either original research papers or extended abstracts of work submitted/accepted/published elsewhere. Accepted original research papers will be invited for publication in a proceedings volume.

Here’s how to submit papers. Two types of submissions are accepted, which will be reviewed to the same standards:

Proceedings Track. Original contributions of high quality work consisting of a 5–12 page extended abstract that provides evidence for results of genuine interest, and with enough detail to allow the program committee to assess the merits of the work. Submissions of works in progress are encouraged, but must be more substantial than a research proposal.

Non-Proceedings Track. Descriptions of high-quality work submitted or published elsewhere will also be considered, provided the work is recent and relevant to the conference. The work may be of any length, but the program committee members may only look at the first 3 pages of the submission, so you should ensure these pages contain sufficient evidence of the quality and rigor of your work.

Submissions should be prepared using LaTeX, and must be submitted in PDF format. Submission is currently open, and can be perfomed at the following web page:

One or more best paper awards may be given out at the discretion of the PC chairs. Selected contributions will be offered extended keynote slots in the program.

3 Responses to Applied Category Theory 2020 (Part 2)

  1. Toby Bartels says:

    There is definitely something to be said for hanging around all day in person with people that are interesting to talk with. But another benefit of holding a conference virtually is the reduced carbon footprint of the travel that's not happening.

    • John Baez says:

      Right. Coronavirus is pushing academics in droves toward reducing their travel, just as needed for the climate crisis. So at ACT2020 we’re going to explore new ways to make online conference interesting—like online chat rooms.

  2. John Baez says:

    The deadline for submitting a paper to give a talk is May 10, not May 16 as I’d earlier said.

You can use Markdown or HTML in your comments. You can also use LaTeX, like this: $latex E = m c^2 $. The word 'latex' comes right after the first dollar sign, with a space after it.
