Artin-Schreier geproci configurations in projective spaces of arbitrary dimension

Luca Chiantini, Lucja Farnik, Giuseppe Favacchio +4

We construct finite geproci sets in every projective dimension and in every positive characteristic by introducing $F_{N}$ -Artin-Schreier configurations. In $P^{3}$ ,…

Enumerative geometry of skew lines in $P^{3}$ with a given associated finite group

Luca Chiantini, Łucja Farnik, Giuseppe Favacchio +4

For any finite set $L$ of 3 or more skew lines in $P_{K}^{3}$ over an algebraically closed field $K$ of arbitrary characteristic, there is a ca…

Weddle schemes

Luca Chiantini, Łucja Farnik, Giuseppe Favacchio +4

The classical Weddle surface is the locus of vertices of quadric cones through six points in $P^{3}$ in linear general position. Equivalently, it is the closure of the locus…
