Covering radius of RM(4,8)

Valérie Gillot, Philippe Langevin

We propose an effective version of the lift by derivation, an invariant that allows us to provide the classification of B(5,6,8)=RM(6, 8)/RM(4,8). The main consequence is to establ…

The $p$ -Adic Valuations of Weil Sums of Binomials

Daniel J. Katz, Philippe Langevin, Sangman Lee +1

We investigate the $p$ -adic valuation of Weil sums of the form $W_{F, d} (a) = \sum_{x \in F} ψ (x^{d} - a x)$ , where $F$ is a finite field of characteristic $p$ , $ψ$ is the canonical addi…
