Determinantal computation of minimal local GADs

Oriol Reig Fité, Daniele Taufer

We study local generalized additive decompositions (GADs) of homogeneous polynomials and their associated points schemes through their local inverse systems. We verify that their c…

Generalized Additive Decompositions of Symmetric Tensors

Enrica Barrilli, Bernard Mourrain, Daniele Taufer

This article addresses the Generalized Additive Decomposition (GAD) of symmetric tensors, that is, degree- $d$ forms $f \in S_{d}$ . From a geometric perspective, a GAD corre…

The Hessian of elliptic curves as a Lattès map

Marzio Mula, Federico Pintore, Daniele Taufer

We prove that the Hessian transformation of elliptic curves, both as an action on $j$ -invariants and on the Hesse pencil, is a rigid Lattès map fitting into a reduced diagram, henc…

Elliptic curves over Hasse pairs

Eleni Agathocleous, Antoine Joux, Daniele Taufer

We call a pair of distinct prime powers $(q_{1}, q_{2}) = (p_{1}^{a_{1}}, p_{2}^{a_{2}})$ a Hasse pair if $∣ q_{1} - q_{2} ∣ \leq 1$ . For such pairs, we study the relation between the set…
