Topic: Project idea: Stone duality


Sam van G (Mar 25 2024 at 09:57):

I will suggest a number of projects related to Stone duality in my talk , you can look at the very last slide if you want spoilers! And come talk to me.

List of possible projects (see my talk this afternoon for details):

  1. Cut down the sober-spatial equivalence
  2. Complete the proof of Birkhoff's theorem
  3. The various equivalent definitions of profinite types
  4. Work towards the Mile-Stones
  5. For the brave: (Finite) Hochster's theorem
  6. Priestley duality
  7. Open mapping theorem and semantic interpolation

Great talk! Could you please upload a [handout] version of your slides?

Thanks @Flo (Florent Schaffhauser) ! Done, and corrected a few typos.

Hi, I'm actually working on the formalisation of stone duality, would you like to talk about it sometime?

Sam van G (Mar 27 2024 at 06:52):

Sure! Come find me any time today

Just now, I pushed a commit to our repository that makes
