Noetherian ring
Definition for commutative rings
Symbol-free definition
A commutative unital ring is termed Noetherian if it satisfies the following equivalent conditions:
- Ascending chain condition on ideals: Any ascending chain of ideals stabilizes after a finite length
- Every ideal is finitely generated

Definition for non-commutative rings
For non-commutative, there are two notions:
- left Noetherian ring must satisfy the ascending chain condition on left ideals
- right Noetherian ring must satisfy the ascending chain condition on right ideals
