| May 16, 2023 at 9:39 | comment | added | Henri Johnston | According to Remark 1 in Prasad, Dipendra, A refined notion of arithmetically equivalent number fields, and curves with isomorphic Jacobians. Adv. Math. 312, 198-208 (2017). Zbl 1430.11153, the above example of Scott is the `only' known example (i.e. ignoring examples that can be constructed from Scott's example in a trivial way). | |
