Effective existence of primitive k-normal elements via affine spaces

Josimar J. R. Aguirre, Sarah F. M. Mazzini, Victor G. L. Neumann

Let $F_{q^{n}}$ be the finite field with $q^{n}$ elements. An element $α \in F_{q^{n}}$ is $k$ -normal over $F_{q}$ if $α$ and its conjugates span an $\mathbb{F}_q…

On the functional graph of $f (X) = X (X^{q - 1} - c)^{q + 1},$ over quadratic extensions of finite fields

Josimar J. R. Aguirre, Abílio Lemos, Victor G. L. Neumann

Let $F_{q}$ be the finite field with $q$ elements. In this paper we will describe the dynamics of the map $f (X) = X (X^{q - 1} - c)^{q + 1},$ with $c \in F_{q}^{*},$ over…

Explicit Computations on the Desingularized Kummer Surface

V. G. Lopez Neumann, Constantin Manoil

We find formulas for the birational maps from a Kummer surface K and its dual K^* to their common minimal desingularization S. We show how the nodes of K blow up. Then we give a de…
