More Arithmetic Fundamental Lemma conjectures: the case of Bessel subgroups
Pages: 2279 – 2336
We define some formal moduli spaces of quasi-isogenies of isoclinic $p$-divisible groups with a non-reductive group as the “structure group”. We then formulate new Arithmetic Fundamental Lemma conjectures for Bessel subgroups in the context of the arithmetic Gan–Gross–Prasad conjectures. Some (very limited) evidence is presented.
