NettetIn algebra, a domain is a nonzero ring in which ab = 0 implies a = 0 or b = 0. ( Sometimes such a ring is said to "have the zero-product property".) Equivalently, a domain is a ring in which 0 is the only left zero divisor (or equivalently, the only right zero divisor). A commutative domain is called an integral domain. Mathematical literature contains … Nettet7. apr. 2024 · This fact can be generalized to arbitrary integral domains by expressing them as intersections of overrings which admit a unique minimal overring.
