A commutative ring is a ring whose multiplication is commutative. .
The real numbers can be extended to a wheel, as can any commutative ring.
Let A{\displaystyle A} be a commutative ring and P{\displaystyle P} an A-module.
As examples, there are several forgetful functors from the category of commutative rings.
In a commutative ring the invertible elements, or units, form an abelian multiplicative group.
The rings in this article are assumed to be commutative rings with identity.
For example, all ideals in a commutative ring are automatically two-sided, which simplifies the situation considerably.
The integers have additional properties which do not generalize to all commutative rings.
Let R{\displaystyle R} be a commutative ring and fix δ∈ R{\displaystyle\delta\in R.
In mathematics, a Witt vector is an infinite sequence of elements of a commutative ring.
If M andN are two modules over a commutative ring R(for example, two abelian groups, when R Z), Tor functors yield a family of R-modules ToriM, N.
It follows from the Eckmann-Hilton theorem,that a monoid in Ring is just a commutative ring.
Over a commutative ring R with total quotient ring K, a module M is torsion-free if and only if Tor1(K/R, M) vanishes.
As the multiplication of integers is a commutative operation, this is a commutative ring.
If K is a commutative ring instead of a field, then everything that has been said above about linear combinations generalizes to this case without change.
In mathematics, Kähler differentials provide an adaptation of differential forms to arbitrary commutative rings or schemes.
If A{\displaystyle A} is a noncommutative ring, connections on left andright A-modules are defined similarly to those on modules over commutative rings.
One of the central themes of algebraic geometry is the duality of the category of affine schemes and the category of commutative rings.

The algebraic method for constructing the optimal polynomial of the partial function over some commutative rings(in Russian)// Ibidem.
The notion of primary ideals is important in commutative ring theory because every ideal of a Noetherian ring has a primary decomposition, that is, can be written as an intersection of finitely many primary ideals.
The construction generalizes in straightforward manner to the tensor algebra of any module M over a commutative ring.
Noether's paper, Idealtheorie in Ringbereichen(Theory of Ideals in Ring Domains, 1921), is the foundation of general commutative ring theory, and gives one of the first general definitions of a commutative ring.
She also worked closely with Wolfgang Krull, who greatly advanced commutative algebra with his Hauptidealsatz andhis dimension theory for commutative rings.
This allows us to define regularity for all commutative rings, not just local ones: A commutative ring A is said to be a regular ring if its localizations at all of its prime ideals are regular local rings. .

Such a monoidal category is called cocartesian monoidal R-Mod, the category of modules over a commutative ring R, is a monoidal category with the tensor product of modules⊗R serving as the monoidal product and the ring R(thought of as a module over itself) serving as the unit.
In her classic 1921 paper Idealtheorie in Ringbereichen(Theory of Ideals in Ring Domains) Noether developed the theory of ideals in commutative rings into a tool with wide-ranging applications.
