This is a reading group following Denis-Charles Cisinski's book ``Higher Categories and Homotopical Algebra''. Our goals are to learn the theory of ∞-categories with an eye towards higher algebra.
We are meeting Saturdays at 16:30 UTC (09:30 PDT) 17:30 UTC (09:30 PST) (since Daylight Savings ended). Our first meeting was Saturday July 30, 2022. There is a discord server. Please email me if you would like the discord/zoom links.
