iirc, she started with taylor towers of functors, of the sort [math] X\cong P_nX[/math] up to homotopy (or something like that, definitely taylor tower tho). I remember her referencing Kristine Bauer, Johnson and McCarthy. The main thing in the talk was a simple way of creating a tower (don't think it was taylor, but could've been) of a simplicial model category using comonads. There were many diagrams, talking about k-coalgebras where they did something to the effect of [math](...,X)\rightarrow(..., kX)\rightarrow(...,k^nX)[/math] (don't remember what those dots actually were) or something to that effect, and something of [math] \mathcal{\Gamma}(\Gamma,...,...)[/math] where the dots didn't really matter in terms of creating the tower (one of them was an epsilon I think). I don't remember every hearing Postnikov, pro-isomorphism or Bousfield-Kan, maybe fibrations tho (50%). She also had moments where things ended up being the homotopy limit of something. Sorry that's all I remember, my brain's a little fried. While trying to remember this I looked up somethings, and it was kinda related to the first little bit of https://www.sciencedirect.com/science/article/pii/S0001870814004289 and this https://books.google.ca/books?id=O7GqCQAAQBAJ&pg=PA30&lpg=PA30&dq=taylor+tower+kathryn+hess&source=bl&ots=uQSwXIuSeu&sig=ACfU3U0GarzCPffGHxy52MunpDjUhQ6dVg&hl=en&sa=X&ved=2ahUKEwi6uKmSw_PpAhUDUt8KHbKNABMQ6AEwAHoECAgQAQ#v=onepage&q=comonad&f=false

>that doesn't prove anything.
Don't worry, I know. I just feel dumb right now, it's inspiration to work harder

They already cancelled classes (even online one for some fucking strange reason) and only have a select few places open to the public. Great news for me since I was about to have my exam in a few days but due to cancelation, I get to study more and even study ahead.
