Generalized Artin-Schreier polynomials

Natalio H. Guersenzvaig, Fernando Szechtman

Let $F$ be a field of prime characteristic $p$ containing $F_{p^{n}}$ as a subfield. We refer to $q (X) = X^{p^{n}} - X - a \in F [X]$ as a generalized Artin-Schreier polynomial. Suppose that $…

A Closed Formula for the Product in Simple Integral Extensions

Natalio H. Guersenzvaig, Fernando Szechtman

Let $ξ$ be an algebraic number and let $α, β \in Q [ξ]$ . An explicit formula for the coordinates of the product $α β$ is given in terms of the coordinates of $α$ and $β$ and th…
