The April 2026 Oberwolfach Arbeitsgemeinschaft will be on Arithmetic Holonomy Bounds and Applications to Irrationality, and in particular will discuss some of the results of this paper.
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, or rather I almost did but it was first cancelled due to Covid and then went online due to Covid. That workshop asked a lot of participants in terms of background which made it particularly tough to be online rather than in the Black Forest. Hence I’m not sure that I can describe what a usual Arbeitsgemeinschaft is like any 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! A number of people seemed keen on knowing the details of our paper up until the point they learnt it was 220 pages long. But I truly think that many of the ideas can be broken down into bite size chunks which I think makes this topic ideally suited to the intended format. The background for the lectures doesn’t involve much beyond the complex theory of modular forms as well as some complex analysis. To see what we have in mind, you can click here to see an outline of how we have conceived the breakdown of lectures might be. When you apply, you can choose which lecture you (might be) prepared to give, assuming you are given enough advanced warning!
