Norm (mathematics) In mathematics, a norm is a function from a real or complex vector space to the non-negative real numbers that behaves in certain ways like the distance from the origin: it commutes with scaling, obeys a form of the triangle inequality, and is ze ...

, a map that assigns a length or size to a mathematical object, including: ** Vector norm, a map that assigns a length or size to any vector in a vector space ** Matrix norm, a map that assigns a length or size to a matrix ** Operator norm, a map that assigns a length or size to any operator in a function space ** Norm (abelian group), a map that assigns a length or size to any element of an abelian group * Field norm a map in algebraic number theory and Galois theory that generalizes the usual distance norm *

Ideal norm In commutative algebra, the norm of an ideal is a generalization of a norm of an element in the field extension. It is particularly important in number theory since it measures the size of an ideal of a complicated number ring in terms of an ideal i ...
