## Definition

Let $\struct {K, +, \circ}$ be a normed division ring.

Let $V$ be a vector space over $K$.

Let $\norm {\,\cdot\,}$ be a norm on $V$.

Then $\struct {V, \norm {\,\cdot\,} }$ is a **normed vector space**.

## Also known as

When $\norm {\,\cdot\,}$ is arbitrary or not directly relevant, it is usual to denote a **normed vector space** merely by the symbol $V$.

A **normed vector space** is also known as a **normed linear space**.
