A big update on my preprint

Two weeks ago I finally uploaded the new version of my preprint on arxiv: https://arxiv.org/abs/2408.11404. It is now 43 pages instead of 19 pages long because I added a big section on classical spectral curves as introduced by Hitchin. Conversations with Hannah Larson and Sameera Vemulapalli (see their preprint https://arxiv.org/abs/2408.12678) helped me realized that the key technical player in the background is the restricted Hitchin map. There is a section on this map but I am currently investigating it in more detail.
