Rank-metric codes, linear sets, and their duality

J Sheekey, G Van de Voorde - Designs, Codes and Cryptography, 2020 - Springer

The geometry of one-weight codes in the sum-rank metric

A Neri, P Santonastaso, F Zullo - Journal of Combinatorial Theory, Series A, 2023 - Elsevier
We provide a geometric characterization of k-dimensional F q m-linear sum-rank metric
codes as tuples of F q-subspaces of F qm k. We then use this characterization to study one …

Linear sets on the projective line with complementary weights

V Napolitano, O Polverino, P Santonastaso, F Zullo - Discrete Mathematics, 2022 - Elsevier
Linear sets on the projective line have attracted a lot of attention because of their link with
blocking sets, KM-arcs and rank-metric codes. In this paper, we study linear sets having two …

[HTML][HTML] On the number of roots of some linearized polynomials

O Polverino, F Zullo - Linear Algebra and its Applications, 2020 - Elsevier
Linearized polynomials appear in many different contexts, such as rank metric codes,

On the minimum size of linear sets

S Adriaensen, P Santonastaso - arXiv preprint arXiv:2301.13001, 2023 - arxiv.org
Recently, a lower bound was established on the size of linear sets in projective spaces, that
intersect a hyperplane in a canonical subgeometry. There are several constructions showing …

[HTML][HTML] Cones from maximum h-scattered linear sets and a stability result for cylinders from hyperovals

S Adriaensen, J Mannaert, P Santonastaso, F Zullo - Discrete Mathematics, 2023 - Elsevier
This paper mainly focuses on cones whose basis is a maximum h-scattered linear set. We
start by investigating the intersection numbers of such cones with respect to the …
