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…
Regularity and symbolic defect of points on rational normal curves
Iman Bahmani Jafarloo, Grzegorz Malara
In this paper we study ideals of points lying on rational normal curves defined in projective plane and projective -space. We give an explicit formula for the value of Casteln…
Negative curves on special rational surfaces
Marcin Dumnicki, Lucja Farnik, Krishna Hanumanthu +4
We study negative curves on surfaces obtained by blowing up special configurations of points in the complex projective palne. Our main results concern the following configurations:…
A matrixwise approach to unexpected hypersurfaces
Marcin Dumnicki, Lucja Farnik, Brian Harbourne +3
The aim of this note is to give a generalization of some results concerning unexpected hypersurfaces. Unexpected hypersurfaces occur when the actual dimension of the space of forms…
New phenomena in the containment problem for simplicial arrangements
Marek Janasz, Magdalena Lampa-Baczyńska, Grzegorz Malara
In this note we consider two simplicial arrangements of lines and ideals of intersection points of these lines. There are intersection points in both cases and the number…
Quartic unexpected curves and surfaces
Thomas Bauer, Grzegorz Malara, Tomasz Szemberg +1
Our research is motivated by recent work of Cook II, Harbourne, Migliore, and Nagel on configurations of points in the projective plane with properties that are unexpected from the…
