In ring theory, a branch of abstract algebra, a commutative ring is a ring in which the multiplication operation is commutative. The study of commutative rings is called commutative algebra.
Some specific kinds of commutative rings are given with the following chain of class inclusions:
- Commutative rings ⊃ integral domains ⊃ integrally closed domains ⊃ unique factorization domains ⊃ principal ideal domains ⊃ Euclidean domains ⊃ fields

Famous quotes containing the word ring:
“Good manners have much to do with the emotions. To make them ring true, one must feel them, not merely exhibit them.”
—Amy Vanderbilt (1908–1974)
