Subschemes of the Border Basis Scheme

In a series of papers, Dr. Le Ngoc Long (University of Passau and Hue University), Prof. Lorenzo Robbiano (Università di Genova) and Prof. Martin Kreuzer develop algorithms to check 0-dimenisonal schemes for certain algebraic and geometric properties. Furthermore, they derive algorithms to compute the locus of all schemes having a particular property inside the moduli space given by the border basis scheme.
