Dihedral reflections and an infinite series of irrational Seshadri constants
Grzegorz Malara, Łukasz Merta, Justyna Szpond +1
Laface and Ugaglia recently constructed an irrational one-point Seshadri constant on the blow-up of at nine very general points by combining a dihedral orbit on $\ma…
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 -Artin-Schreier configurations. In ,…
Enumerative geometry of skew lines in with a given associated finite group
Luca Chiantini, Łucja Farnik, Giuseppe Favacchio +4
For any finite set of 3 or more skew lines in over an algebraically closed field of arbitrary characteristic, there is a ca…
From a Pascal construction to the Burkhardt quartic
Tomasz Szemberg, Justyna Szpond
We continue the study of Pascal-type residual constructions in projective four-space. Starting from two -tuples of hyperplanes in such that the diagonal inters…
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 in linear general position. Equivalently, it is the closure of the locus…
