CAUTION: The Sender of this email is not from within Dalhousie. Dear members of the Category Theory community, 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, act2020.mit.edu. 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: act2020.mit.edu/#papers. ** IMPORTANT DATES (all in 2020) ** * Submission of contributed papers: May 16 * Acceptance/Rejection notification: June 07 * Tutorial day: July 5 * Main conference: July 6-10 Registration will now be free; please register for the conference ahead of time here: http://act2020.mit.edu/#registration. 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. All the best, The ACT committee [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
