CAUTION: The Sender of this email is not from within Dalhousie. Dear colleagues, Given the current pandemic situation, we regret to inform that the workshop ∞-categories and their applications to be held at the Max Planck Institute for Mathematics, Bonn, Germany on August 17-21, 2020, has had to change form. Previously, it was scheduled to consist of four minicourses, eight plenary talks, and several contributed talks. We have decided to cancel the plenary and contributed talks. The minicourses will be maintained at the same dates, but in an online form. The minicourses are: Minicourse 1: Models for homotopical higher categories, by Bergner, Julie (University of Virginia) Minicourse 2: Introduction to ∞-operads by Haugseng, Rune (NTNU) Minicourse 3: Higher Categories and Algebraic K-Theory by Nikolaus, Thomas (WWU Münster) Minicourse 4: Exodromy and compactifications of arithmetic schemes by Barwick, Clark (University of Edinburgh) All interested in attending should register via the website https://www.mpim-bonn.mpg.de/node/10159 Technical details and the schedule will appear in the website when we are closer to the dates. Best, Hongyi Chu and Bruno Stonek [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
