4. (mathematics) A function which satisfies a particular set of formal conditions, created to generalize the notion of the length of a vector. Formally, a real-valued function on a vector space, generally denoted ${\displaystyle v\mapsto \left|v\right|}$ or ${\displaystyle v\mapsto \left\|v\right\|}$, that satisfies the following properties:
   1. if ${\displaystyle v\neq 0}$ then ${\displaystyle \left\|v\right\|\neq 0}$;
   2. given a scalar ${\displaystyle k}$, ${\displaystyle \left\|kv\right\|=\left|k\right|\cdot \left\|v\right\|}$, where ${\displaystyle \left|k\right|}$ is the absolute value of ${\displaystyle k}$;
   3. given two vectors ${\displaystyle v,w}$, ${\displaystyle \left\|v+w\right\|\leq \left\|v\right\|+\left\|w\right\|}$ (the triangle inequality).
5. (mathematics) Any of several generalizations of the above: a matrix norm, operator norm, etc.
6. (chess) A high level of performance in a chess tournament, several of which are required for a player to receive a title.
