Infinite families of irreducible polynomials over finite fields
Infinite families of irreducible polynomials over finite fields
Let $p$ be a prime number and $q$ a power of $p$. Let $\fq$ be the finite field with $q$ elements. For a positive integer $n$ and a polynomial $\varphi(X)\in\fq[X]$, let $d_{n,\varphi}(X)$ denote the denominator of the $n$th iterate of $\frac{1}{\varphi(X)}$. The polynomial $\varphi(X)$ is said to be inversely stable …
