Geometrically vertex decomposable star configurations

Susan M. Cooper, Emanuela Marangone, Elena Guardo +1

The goal of this paper is to determine how the family of ideals of star configurations intersects with the class of geometrically vertex decomposable ideals. The main result of thi…

Some Taylor varieties with null Hessian

Thais Gomes Ribeiro, Elena Guardo, Manuela Muzika Dizdarević +3

Taylor varieties $T_{d, e, m}^{n}$ arise from Taylor expansion of rational functions in $n$ variables. Among them, we look for non-defective hypersurfaces. We prove that the…

Interpolation matrices and jumping lines of logarithmic bundles

Elena Guardo, Graham Keiper, Grzegorz Malara

We study jumping lines loci of logarithmic bundles associated with finite sets of points in the projective plane. Using the interpolation matrix introduced in [DMTG25], we describe…

Splittings of Ideals of Points in $P^{1} \times P^{1}$

Elena Guardo, Graham Keiper, Adam Van Tuyl

Let $I_{X}$ be the bihomogeneous ideal of a finite set of points $X \subseteq P^{1} \times P^{1}$ . The purpose of this note is to consider ``splitting…

The Waldschmidt constant of a standard $k$ -configuration in $P^{2}$

Maria Virginia Catalisano, Giuseppe Favacchio, Elena Guardo +1

A $k$ -configuration of type $(d_{1}, \dots, d_{s})$ is a specific set of points in $P^{2}$ that has a number of algebraic and geometric properties. For example, the graded Bett…

Hadamard products of symbolic powers and Hadamard fat grids

I. Bahmani Jafarloo, C. Bocci, E. Guardo +1

In this paper we address the question if, for points $P, Q \in P^{2}$ , $I (P)^{m} ⋆ I (Q)^{n} = I (P ⋆ Q)^{m + n - 1}$ and we obtain different results according to the numb…
