A remark on normal bases
We quote the author's words: ``In \textit{H. P. Schlickewei} and \textit{S. A. Stepanov} [J. Number Theory 44, 30-40 (1993; Zbl 0780.11053), Theorem 1.1], the authors constructed a normal basis of a cyclic extension field \(\mathcal L\) of \(\mathbb{Q}\). The content of this note is a simpler construction that works in the general abelian case, too''.
