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…

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…

Matrixwise (approach to unexpected hypersurfaces) Reloaded

Marcin Dumnicki, Grzegorz Malara, Halszka Tutaj-Gasińska

In the paper we provide a new method of proving the existence of a hypersurface of degree in , with a general point of multiplicity and vanishing at a given s…

Postulation of lines in P3 revisited

Marcin Dumnicki, Mikolaj Le Van, Grzegorz Malara +3

The purpose of the present note is to provide a new proof ot the well-known result due to Hartshorne and Hirschowitz to the effect that general lines in projective spaces have good…

Construction of free curves by adding osculating conics to a given cubic curve

Alexandru Dimca, Giovanna Ilardi, Grzegorz Malara +1

In the present article we construct new families of free and nearly free curves starting from a plane cubic curve and adding some of its hyperosculating conics. We present resu…

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 , and we obtain different results according to the numb…
