Good iso-dual AG-codes from towers of function fields

María Chara, Ricardo Podestá, Luciane Quoos +1

We present a simple method to establish the existence of asymptotically good sequences of iso-dual AG-codes. A key advantage of our approach, beyond its simplicity, is its flexibil…

Connected components and non-bipartiteness of generalized Paley graphs

Ricardo A. Podestá, Denis E. Videla

In this work we consider the class of Cayley graphs known as generalized Paley graphs (GP-graphs for short) given by $Γ (k, q) = C a y (F_{q}, {x^{k} : x \in F_{q}^{*}})$ , w…

Spectral properties of generalized Paley graphs

Ricardo A. Podestá, Denis E. Videla

We study the spectrum of generalized Paley graphs $Γ (k, q) = C a y (F_{q}, R_{k})$ , undirected or not, with $R_{k} = {x^{k} : x \in F_{q}^{*}}$ where $q = p^{m}$ with $p$ prime and $k\mid…
