Definition

Let $\EE$ and $\FF$ be affine spaces with difference spaces $E$ and $F$ respectively.

Let $\LL: \EE \to \FF$ be an affine transformation.


The associated linear transformation $L: E \to F$ of difference spaces is called the tangent map of $\LL$.


Also known as

The tangent map of $\LL$ is also known as the linear part of $\LL$.
