“…1 Finally, let us mention how the applications of our theory connect to earlier work. To our best knowledge, over number fields Theorem 1.3 is the first general result of this kind, except for the work [7], [11] on curves with a p-isogeny. In contrast, the p-parity conjecture over ޑ was known in almost all cases, thanks to Birch, Stephens, Greenberg and Guo [3], [15], [16] (E CM), Kramer, Monsky [22], [26] (p D 2), Nekovář [28] (p potentially ordinary or potentially multiplicative) and Kim [18] (p supersingular).…”
