On $r$ -primitive $k$ -normal polynomials with two prescribed coefficients

Avnish K. Sharma, Mamta Rani, Sharwan K. Tiwari +1

This article investigates the existence of an $r$ -primitive $k$ -normal polynomial, defined as the minimal polynomial of an $r$ -primitive $k$ -normal element in $F_{q^{n}}$ , w…

Inverses of $r$ -primitive $k$ -normal elements over finite fields

Mamta Rani, Avnish K. Sharma, Sharwan K. Tiwari +1

Let $r$ , $n$ be positive integers, $k$ be a non-negative integer and $q$ be any prime power such that $r ∣ q^{n} - 1.$ An element $α$ of the finite field $F_{q^{n}}$ is called…

Primitive Normal Values of Rational Functions over Finite Fields

Avnish K. Sharma, Mamta Rani, Sharwan K. Tiwari

In this paper, we consider rational functions $f$ with some minor restrictions over the finite field $F_{q^{n}},$ where $q = p^{k}$ for some prime $p$ and positive integer $k$ .…
