Sets computing the symmetric tensor rank
Edoardo Ballico, Luca Chiantini
Let n_d denote the degree d Veronese embedding of a projective space P^r. For any symmetric tensor P, the 'symmetric tensor rank' sr(P) is the minimal cardinality of a subset A of…

A criterion for detecting the identifiability of symmetric tensors of size three
Edoardo Ballico, Luca Chiantini
We prove a criterion for the identifiability of symmetric tensors of type , times, whose rank is bounded by . The criterion is based on…
