Polar degrees and closest points in codimension two

Martin Helmer, Bernt Ivar Utstøl Nødland

Suppose that $X_{A} \subset P^{n - 1}$ is a toric variety of codimension two defined by an $(n - 2) \times n$ integer matrix $A$ , and let $B$ be a Gale dual of $A$ . In this paper…

The Hilbert scheme of 11 points in A^3 is irreducible

Theodosios Douvropoulos, Joachim Jelisiejew, Bernt Ivar Utstøl Nødland +1

We prove that the Hilbert scheme of 11 points on a smooth threefold is irreducible. In the course of the proof, we present several known and new techniques for producing curves on…

Secants, bitangents, and their congruences

Kathlén Kohn, Bernt Ivar Utstøl Nødland, Paolo Tripoli

A congruence is a surface in the Grassmannian $Gr (1, P^{3})$ of lines in projective $3$ -space. To a space curve $C$ , we associate the Chow hypersurface in $\mathrm{G…
