Prüfer domain
A commutative integral domain
is a Prüfer domain if every finitely generated
nonzero ideal of is invertible.
Let denote the localization of at . Then the following statements are equivalent:
- •
i) is a Prüfer domain.
- •
ii) For every prime ideal
in , is a valuation domain.
- •
iii) For every maximal ideal
in , is a valuation domain.
A Prüfer domain is a Dedekind domain if and only if it is Noetherian.
If is a Prüfer domain with quotient field , then any domain such that is Prüfer.
