$(r, s)$ -sets from Desarguesian ovoids

Francesco Pavese

An $(r, s)$ - $s e t$ in $PG (n, q)$ is a set of points, say $X$ , such that each $s$ -dimensional projective subspace contains at most $r$ points of $X$ …

Segre Varieties and Desarguesian Spreads

Antonio Cossidente, Giuseppe Marino, Francesco Pavese +2

Let $PG (n - 1, q)$ denote the $(n - 1)$ -dimensional projective space over $F_{q}$ . We investigate the intersection of two Desarguesian $(h - 1)$ -spreads of $\mathrm{PG}(kh…

On pseudo-arcs from normal rational curve and additive MDS codes

Francesco Pavese, Paolo Santonastaso

Let $PG (k - 1, q)$ be the $(k - 1)$ -dimensional projective space over the finite field $F_{q}$ . An arc in $PG (k - 1, q)$ is a set of points with the property that…
