domain (of definition)
31Domain (biology) — This article is about the domain rank in biological classification. For other uses, see Domain (disambiguation) …
32Dedekind domain — In abstract algebra, a Dedekind domain or Dedekind ring, named after Richard Dedekind, is an integral domain in which every nonzero proper ideal factors into a product of prime ideals. It can be shown that such a factorization is then necessarily …
33Protein domain — Pyruvate kinase, a protein from three domains (PDB 1pkn) A protein domain is a part of protein sequence and structure that can evolve, function, and exist independently of the rest of the protein chain. Each domain forms a compact three… …
34Euclidean domain — In abstract algebra, a Euclidean domain (also called a Euclidean ring) is a type of ring in which the Euclidean algorithm applies. A Euclidean domain is a specific type of integral domain, and can be characterized by the following (not… …
35Operational definition — The operational definition of a peanut butter sandwich might be simply the result of putting peanut butter on a slice of bread with a butter knife and laying a second equally sized slice of bread on top An operational definition defines something …
36Public domain — This article is about public ownership of creative works. For use in relationship to public lands, see Public domain (land). For how the public domain applies to Wikipedia, see Wikipedia:Public domain. Intellectual property law …
37Integral domain — In abstract algebra, an integral domain is a commutative ring that has no zero divisors,[1] and which is not the trivial ring {0}. It is usually assumed that commutative rings and integral domains have a multiplicative identity even though this… …
38Unique factorization domain — In mathematics, a unique factorization domain (UFD) is, roughly speaking, a commutative ring in which every element, with special exceptions, can be uniquely written as a product of prime elements, analogous to the fundamental theorem of… …
39Fundamental domain — In geometry, the fundamental domain of a symmetry group of an object or pattern is a part of the pattern, as small as possible, which, based on the symmetry, determines the whole object or pattern. The set of orbits of the symmetry group define a …
40Well-definition — For other uses, see Definition (disambiguation). In mathematics, well definition is a mathematical or logical definition of a certain concept or object (a function, a property, a relation, etc.) which uses a set of base axioms in an entirely… …
