This category contains results about linear isometries.
Definitions specific to this category can be found in Definitions/Linear Isometries.

Let $\struct {X, \norm \cdot_X}$ and $\struct {Y, \norm \cdot_Y}$ be normed vector spaces.

Let $T : X \to Y$ be a linear transformation.


We say that $T$ is a linear isometry if and only if:

$\norm {T x}_Y = \norm x_X$

for each $x \in X$.
