[Note from moderator: posted on behalf of Emily Riehl] We're delighted to announce the HoTTEST Summer School, which will take place online everywhere in the world during the months of July and August 2022. Please help us spread the word to any students you might know who would be interested in learning more about homotopy type theory, univalent foundations, and computer proof assistants. The school will run both synchronously and asynchronously. The lectures will be delivered live (between 2:30-4pm UTC) and paired with various tutorial sessions run by teaching assistants. The course will also feature a discord-based all-hours Q&A and an online archive of all course materials so that participants can follow along on their own schedule. This school is for everyone and anyone with some familiarity with abstract mathematics or theoretical computer science and an itching to learn about homotopy type theory. Our goal is to make homotopy type theory accessible to, and inclusive of, everyone who is interested, regardless of cultural background, age, ability, formal education, ethnicity, gender identity, or expression. We believe HoTT is for everyone, and are committed to fostering a kind, inclusive environment. There are no costs involved in participating. The first part of the course will include parallel introductions to homotopy type theory and formalization given by Ulrik Buchholtz, Martin Hotzel Escardo, Dan Licata, Anders Mortberg, Paige North, Emily Riehl, and Egbert Rijke. The summer school will then close with a series of colloquia introducing more advanced topics and exciting areas for further study delivered by Pierre Cagne, Favonia, Jonas Frey, Jon Sterling, and Chaitanya Leena Subramaniam. A team of teaching assistants which includes Elisabeth Bonnevier, Chris Grossack, Tom de Jong, Jarl G. Taxeras Flaten, Artem Gureev, Perry Hart, Astra Kolomatskaia, Amelia Liao, Jacob Neumann, Johannes Schipp von Branitz, and Christopher Stough-Brown among others, will lead problem sessions and assist students with exercises. A central aim of the summer school is to build community among all of the participants, irrespective of geography. To further this, we will hold some online social events (e.g. game nights) for the summer school staff and participants. More details about the course logistics and the scientific program will be announced soon on the summer school website: https://uwo.ca/math/faculty/kapulkin/seminars/hottest_summer_school_2022.htm... In the meanwhile, we invite everyone to join us on the summer school Discord group to hang out and get to know one another: https://discord.gg/tkhJ9zCGs9 If you would like to participate in some background surveys that will shape the design of the curriculum, please register for the Discord by May 15th, but students are also welcome to join in at any time. On behalf of the organizers, Carlo Angiuli, Dan Christensen, Martin Hotzel Escardo, Chris Kapulkin, Dan Licata, Emily Riehl, Egbert Rijke [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
