Variants of the Erdős distinct sums problem and variance method

Simone Costa, Stefano Della Fiore, Andrea Ferraguti

Let $Σ = {a_{1}, \dots, a_{n}}$ be a set of positive integers with $a_{1} < \dots < a_{n}$ such that all $2^{n}$ subset sums are pairwise distinct. A famous conjecture of Erdős states tha…

Number Theoretical Locally Recoverable Codes

Andrea Ferraguti, Dorian Goldfeld, Giacomo Micheli

In this paper we give constructions for infinite sequences of finite non-linear locally recoverable codes $C \subseteq i = 1 \prod N F_{q_{i}}$ over a product o…

Abelian dynamical Galois groups for unicritical polynomials

Andrea Ferraguti, Carlo Pagano

Andrews and Petsche proposed in 2020 a conjectural characterization of all pairs $(f, α)$ , where $f$ is a polynomial over a number field $K$ and $α \in K$ , such that the dynamical Ga…
