Definition
Symbol-free definition
An integral domain is termed a Dedekind domain if it satisfies the following equivalent conditions:
- It is a Noetherian normal domain of Krull dimension 1
- Every nonzero ideal is invertible in the field of fractions and can be expressed uniquely as a product of prime ideals
Relation with other properties
Stronger properties
- Euclidean domain
- Principal ideal domain
- Polynomial ring over a field
- Ring of integers in a number field
Weaker properties
Conjunction with other properties
Any unique factorization domain which is also a Dedekind domain, is also a principal ideal domain.
