Reading Group on Arithmetic Universes

With Alexander Oldenziel, Joost van Dijk and a few others we have an informal weekly reading sessions on Arithmetic Universes and Goedelś incompleteness theorem in Utrecht and Amsterdam. If you are in the Randstad area, and interested in this sort of things, send me an email.



CARGO

I am one of the organizers of category theory reading group (CARGO). The meetings takes place at the school of computer science on a weekly basis. The particiants are mostly PhD students and research fellows in theoretical computer science.

Read more about it here .

  • From 2015-2017, CARGO meetings used to takes place at the school of computer science on every Tuesday at 2:00 p.m. in room 245. For the academic year of 2017-2018 we have our meetings on Thursdays at 11:00 a.m. in the same room.
  • Here is the archive of talks: CARGO archive. Feel free to subscribe to our mailing list. Let me also mention the archive of our Theory Seminars talks on Fridays. I have given four talks in theory seminars and numerous talks in CARGO. Sometimes I find enough time and I write the notes of the talks which can be found in below.
  • Here is a list of topics considered to be discussed in Autumn 2017 in Category Reading Group seminars as well as informal archive for suggested topics since Summer 2015: Potential topics and Informal archive.



Expository Papers And Notes

Writing notes helps me to grasp a mathematical concept or construction and they become less elusive in my mind. Here are the notes from some of my talks for which I had time to type them up. Any reports of mistakes and errors from the reader are always welcome.
