On Strassen's rank additivity for small three-way tensors

Jarosław Buczyński, Elisa Postinghel, Filip Rupniewski

We address the problem of the additivity of the tensor rank. That is for two independent tensors we study if the rank of their direct sum is equal to the sum of their individual ra…

Secant varieties of Segre-Veronese embeddings of (P^1)^r

Antonio Laface, Elisa Postinghel

We use a double degeneration technique to calculate the dimension of the secant variety of any Segre-Veronese embedding of (P^1)^r

Secant Degree of Toric Surfaces and Delightful Planar Toric Degenerations

Elisa Postinghel

The -secant degree is studied with a combinatorial approach. A planar toric degeneration of any projective toric surface corresponds to a regular unimodular triangulation $D…
