High Order Singular Value Decomposition for Plant Biodiversity Estimation
Alessandra Bernardi, Martina Iannacito, Duccio Rocchini
We propose a new method to estimate plant biodiversity with R{é}nyi and Rao indexes through the so called High Order Singular Value Decomposition (HOSVD) of tensors. Starting from…
Geometric conditions for strict submultiplicativity of rank and border rank
Edoardo Ballico, Alessandra Bernardi, Fulvio Gesmundo +2
The -rank of a point in projective space is the minimal number of points of an algebraic variety whose linear span contains . This notion is naturally submultiplicati…
Strict inclusions of high rank loci
Edoardo Ballico, Alessandra Bernardi, Emanuele Ventura
For a given projective variety , the high rank loci are the closures of the sets of points whose -rank is higher than the generic one. We show examples of strict inclusion be…
