Editing Domain (section)

== Mathematics ==
* [[Domain (mathematical analysis)]], an open connected set
* [[Domain (ring theory)]], a non-trivial ring without left or right nonzero zero divisors
** [[Integral domain]], a non-trivial commutative ring without nonzero zero divisors
*** [[Atomic domain]], an integral domain in which every nonzero non-unit is a finite product of irreducible elements
*** [[Bézout domain]], an integral domain in which the sum of two principal ideals is again a principal ideal
*** [[Euclidean domain]], an integral domain which allows a suitable generalization of the Euclidean algorithm
*** [[Dedekind domain]], an integral domain in which every nonzero proper ideal factors into a product of prime ideals
*** [[GCD domain]], an integral domain in which every two non-zero elements have a greatest common divisor
*** [[Principal ideal domain]], an integral domain in which every ideal is principal
*** [[Unique factorization domain]], an integral domain in which every non-zero element can be written as a product of irreducible elements in essentially a unique way
* [[Domain of a function]], the set of input values for which the (total) function is defined
** [[Domain of definition]] of a partial function
** [[Natural domain]] of a partial function

* Domain of an [[algebraic structure]], the set on which the algebraic structure is defined
* [[Domain of discourse]], the set of entities over which logic variables may range
* [[Domain theory]], the study of certain subsets of continuous lattices that provided the first denotational semantics of the lambda calculus
* [[Frequency domain]], the analysis of mathematical functions with respect to frequency, rather than time
