## Definition

Let $\struct {G, +_G, \circ}_K$ be a vector space, where:

- $\struct {K, +_K, \times_K}$ is a field

- $\struct {G, +_G}$ is an abelian group $\struct {G, +_G}$

- $\circ: K \times G \to G$ is a binary operation.

Then the field $\struct {K, +_K, \times_K}$ is called the **scalar field** of $\struct {G, +_G, \circ}_K$.

If the **scalar field** is understood, then $\struct {G, +_G, \circ}_K$ can be rendered $\struct {G, +_G, \circ}$.

## Also known as

A **scalar field**, as used in this context, is also known as a **ground field**.
