Let $\struct {F, +, \times}$ and $\struct {K, \oplus, \otimes}$ be fields.

Let $\phi: F \to K$ be a mapping such that both $+$ and $\times$ have the morphism property under $\phi$.

That is, $\forall a, b \in F$:

 $\text {(1)}: \quad$ $\ds \map \phi {a + b}$ $=$ $\ds \map \phi a \oplus \map \phi b$ $\text {(2)}: \quad$ $\ds \map \phi {a \times b}$ $=$ $\ds \map \phi a \otimes \map \phi b$

Then $\phi: \struct {F, +, \times} \to \struct {K, \oplus, \otimes}$ is a field homomorphism.
