Some remarks on degeneracy of tridimensional tensors
Alessandro Gimigliano, Monica IdÃ
We study tridimensional tensors on the complex field from the point of view of hypermatrices, taking into consideration the problem of determining whether they are degenerate or no…

Postulation for 2-superfat points in the plane
Stefano Canino, Maria Virginia Catalisano, Alessandro Gimigliano +2
We study the postulation of 0-dimensional schemes given by unions of 2-superfat points in general position in the plane, i.e., the union of local schemes defined by the intersectio…

Superfat points and associated tensors
Stefano Canino, Maria Virginia Catalisano, Alessandro Gimigliano +1
We consider 0-dimensional schemes supported at a single point in n-space that are m-symmetric, i.e. that intersect any smooth curve passing through the point with length m, and the…
