Hadamard ranks of algebraic varieties
Dario Antolini, Guido Montúfar, Alessandro Oneto
Motivated by the study of decompositions of tensors as Hadamard products (i.e., coefficient-wise products) of low-rank tensors, we introduce the notion of Hadamard rank of a given…
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…
Non-defectivity of Segre-Veronese varieties
Hirotachi Abo, Maria Chiara Brambilla, Francesco Galuppi +1
We prove that Segre-Veronese varieties are never secant defective if each degree is at least three. The proof is by induction on the number of factors, degree and dimension. As a c…
