Fields with no everywhere good abelian varieties

Number Theory 2026-03-23 v2

Abstract

We extend methods of Fontaine, Abrashkin and Schoof to obtain criteria determining number fields K over which no non-zero abelian variety with everywhere good reduction exists. As an application, under the GRH, we find 24744 such fields of various degrees up to 16.
