Algebraic surfaces as Hadamard products of curves
Dario Antolini, Edoardo Ballico, Alessandro Oneto
We study projective surfaces in which can be written as Hadamard product of two curves. We show that quadratic surfaces which are Hadamard product of two lines are s…
Projective surfaces not as Hadamard products and the dimensions of the Hadamard joins
Edoardo Ballico
We study the dimensions of Hadamard products of varieties if we allow to modify of them by the action of a general projective linear transformation. We also prove th…
Terracini loci and a codimension one Alexander-Hirschowitz theorem
Edoardo Ballico, Maria Chiara Brambilla, Claudio Fontanari
The Terracini locus is the locus of all finite subsets of of cardinality such that , $h^0(\mathcal{I…
Hyperelliptically fibred surfaces with nodes
Edoardo Ballico, Elizabeth Gasparim, Bruno Suzuki
Using elementary methods of algebraic geometry, we present constructions of hyperelliptically fibred surfaces containing nodal fibres.
Minimal Terracini loci in the plane: gaps and non-gaps
Edoardo Ballico, Maria Chiara Brambilla
We study minimally Terracini finite sets of points in the projective plane and we prove that the sequence of the cardinalities of minimally Terracini sets can have any number of ga…
Tensoring by a plane maintains secant-regularity in degree at least two
Edoardo Ballico, Alessandra Bernardi, Tomasz Mańdziuk
Starting from an integral projective variety equipped with a very ample, non-special and not-secant defective line bundle , the paper establishes, under certain co…
