Artin-Schreier curves given by ${\mathbb{F}}_q$-linearized polynomials

Daniela Oliveira, F. E. Brochero Martínez

Let ${\mathbb{F}}_q$ be a finite field with $q$ elements, where $q$ is a power of an odd prime $p$. In this paper we associate circulant matrices and quadratic forms with the Artin-Sc…
