In this chapter, we take a closer look at a finite extension
F
<
E
from the point of view that
E
is a vector space over
F
. It is clear, for instance, that any
σ
∈
G
F
(
E
) is a linear operator on
E
over
F
. However, there are many linear operators that are not field automorphisms. One of the most important is multiplication by a fixed element of
E
, which we study next.
