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…

On the Jacobian Scheme of a plane curve
Stefano Canino, Alessandro Gimigliano, Monica Idà
We study the Jacobian scheme of a plane algebraic curve at an ordinary singularity, characterizing it through a geometric property. We compute the Tjurina number for a family of cu…
