Schubert compactifications of matrix pencils

Vincenzo Galgano, Fulvio Gesmundo, Hanieh Keneshlou

The Schubert compactification of a linear space of matrices $L \subseteq Mat_{n \times m}$ is a natural compactification of $L$ in the Grassmannian $Gr (n, n + m)$ . T…

Components of Hilbert Schemes of low degree and smoothable algebras

Maciej Gałązka, Hanieh Keneshlou, Klemen Šivic

In this article, we describe the irreducible components of the Hilbert scheme of $d$ points on $A^{n}$ for $d = 9, 10$ . The main techniques we use are the variety of commuting…

Cactus scheme, catalecticant minors, and scheme theoretic equations

Jarosław Buczyński, Hanieh Keneshlou

The $r$ -th cactus variety of a subvariety $X$ in a projective space generalizes the $r$ -th secant variety of $X$ and it is defined using linear spans of finite subschemes of $X$ of…

Collineation varieties of tensors

Fulvio Gesmundo, Hanieh Keneshlou

In this article, we introduce the $k$ -th collineation variety of a third order tensor. This is the closure of the image of the rational map of size $k$ minors of a matrix of linear…

Equivariant Euler characteristics on permutohedral varieties

Vincenzo Galgano, Hanieh Keneshlou, Mateusz Michalek

By the work of J.Huh, one can interpret binomial coefficients as a solution to an intersection problem on a permutohedral variety $X_{E}$ . Applying Hirzebruch-Riemann-Roch, this inte…

On construction of k-regular maps to Grassmannians via algebras of socle dimension two

Joachim Jelisiejew, Hanieh Keneshlou

A continuous map $C^{n} \to G r (τ, N)$ is $k$ -regular if the $τ$ -dimensional subspaces corresponding to images of any $k$ distinct points span a $τ k$ -dimensional space. For $τ…

On the unirationality of moduli spaces of pointed curves

Hanieh Keneshlou, Fabio Tanturri

We show that $M_{g, n}$ , the moduli space of smooth curves of genus $g$ together with $n$ marked points, is unirational for $g = 12$ and $2 \leq n \leq 4$ and for $g = 13$ and…

Cubic surfaces on the singular locus of the Eckardt hypersurface

Hanieh Keneshlou

The Eckardt hypersurface in $P^{19}$ parameterizes smooth cubic surfaces with an Eckardt point, which is a point common to three of the $27$ lines on a smooth cubic surfac…

Quantitative singularity theory for random polynomials

Paul Breiding, Hanieh Keneshlou, Antonio Lerario

Motivated by Hilbert's 16th problem we discuss the probabilities of topological features of a system of random homogeneous polynomials. The distribution for the polynomials is the…

Determinantal representations of the cubic discriminant

Dominic Bunnett, Hanieh Keneshlou

We compute and study two determinantal representations of the discriminant of a cubic quaternary form. The first representation is the Chow form of the $2$ -uple embedding of $\math…

The unirational components of the strata of genus $11$ curves with several pencils of degree $6$ in $M_{11}$

Hanieh Keneshlou, Frank-Olaf Schreyer

We show that the strata $M_{11, 6} (k) \subset M_{11}$ of $6 -$ gonal curves of genus $11$ , equipped with $k$ mutually independent and type I pencils of degree…

The unirationality of the Hurwitz schemes $H_{10, 8}$ and $H_{13, 7}$

Hanieh Keneshlou, Fabio Tanturri

We show that the Hurwitz scheme $H_{g, d}$ parametrizing $d$ -sheeted simply branched covers of the projective line by smooth curves of genus $g$ , up to isomorphism, is uni…
