On the number of solutions of systems of diagonal equations through diagonal GP-graphs: the general and the Hermitian-form cases

Ricardo A. Podestá, Denis E. Videla

For any $m, s \in N$ , we study the number $N_{m \times s, q} (κ, β)$ of solutions $(x_{1}, \dots, x_{s}) \in (F_{q})^{s}$ of the monic system of diagonal equations $$ X_{1}^{…

On $k$ -th unitary Cayley graphs over finite commutative rings: structure and decompositions

Ricardo A. Podestá, Denis E. Videla

Given $R$ a finite commutative ring with identity and $k \in N$ , we consider the $k$ -th unitary Cayley graph $G_{R} (k) = C a y (R, U_{R, k})$ with $U_{R, k} = {x^{k} : x \in R^{*}}$ ,…

The nature of the spectrum of generalized Paley graphs and weak Waring numbers over finite fields

Ricardo A. Podestá, Denis E. Videla

We consider the family of generalized Paley graphs (GP-graphs for short) $Γ (k, q) = C a y (F_{q}, (F_{q}^{*})^{k})$ , with $q = p^{m}$ and $p$ prime. We characterize all GP-graphs…
