View on Github →feat(ring_theory/dedekind_domain): definitions (#4000)
Defines is_dedekind_domain
in three variants:
is_dedekind_domain
: Noetherian, Integrally closed, Krull dimension 1, thanks to @Vierkantoris_dedekind_domain_dvr
: Noetherian, localization at every nonzero prime is a DVRis_dedekind_domain_inv
: Every nonzero ideal is invertible. TODO: prove that these definitions are equivalent. This PR also includes some misc. lemmas required to show the definitions are independent of choice of fraction field.
