Arbeitsgemeinschaft 2020

The April 2020 Oberwolfach Arbeitsgemeinschaft will be on derived Galois deformation rings and the cohomology of arithmetic groups!

For those who don’t know, the Arbeitsgemeinschaft (“study group”) is different from usual Oberwolfach workshops (or workshops more generally) — the idea is that the participants learn the material and then teach it to each other. I have never actually been to one (please leave a comment on your experience if you have), so I’m not sure that I can describe it better than reproducing the official blurb here:

The Arbeitsgemeinschaften mainly address to non-specialists who want to broaden their outlook on mathematics and to junior researchers who wish to enter a field for future research. Experts are also welcome. The idea is “learning by doing” – similar to the Seminaire Bourbaki. Participants have to volunteer for one of the lectures described in the program of the Arbeitsgemeinschaft. After the deadline for application the organizers choose the actual speakers to give them enough time to understand the subject and to prepare for their lectures.

If you are interested in learning this material, please consider applying! There is currently an ambitious mix of material from the cohomology of arithmetic groups to the Taylor-Wiles method to to derived deformation rings. The expectation is certainly that you are not an expert on all of these topics. (The precise emphasis of the workshop will naturally depend on the exact mix of participants.) Click here to see an outline of how we have conceived what the lectures might be. When you apply, you can choose which lecture you (might be) prepared to give, assuming you are given enough advanced warning! All the links you might need (for applying and other information) can be found here:

2020 Arbeitsgemeinschaft: Derived Galois Deformation Rings and Cohomology of Arithmetic Groups

Note that the timing of this workshop is planned to immediately precede the
Hausdorff Trimester in Bonn of which I have mentioned previously and will give more information about in an upcoming post. Consider going to both!

update: It was pointed out to me that April 4 does not immediately precede May 4 in any reasonable sense of the word.
