A linear algebra approach to cyclic extensions in Galois theory. (English) Zbl 0772.12003
The usual approach to a discussion on cyclic extensions in a beginning course in Galois theory is to derive the results on cyclic extensions as corollaries to the norm and trace theorems. In this note, the author offers an alternate approach based on linear algebra.
