Two number fields are arithmetically equivalent if they have the same Dedekind $\zeta$-functions. Arithmetically equivalent fields share many invariants, such as their degrees, signatures, discriminants, and Galois groups. For a given field, the existence of an arithmetically equivalent sibling depends only on the Galois group.
