On the stabilizer of the graph of linear functions over finite fields

Valentino Smaldore, Corrado Zanella, Ferdinando Zullo

In this paper we will study the action of ${\mathbb{F}}_{q^n}^{2\times 2}$ on the graph of an ${\mathbb{F}}_q$-linear function of ${\mathbb{F}}_{q^n}$ into itself. In particular we will…
