Deformations of Border Bases

Martin Kreuzer, Lorenzo Robbiano

Here we study the problem of generalizing one of the main tools of Groebner basis theory, namely the flat deformation to the leading term ideal, to the border basis setting. After…

Hilbert Function and Betti Numbers of Algebras with Lefschetz Property of Order m

Alexandru Constantinescu

The authors T.Harima, J.C.Migliore, U.Nagel and J.Watanabe characterized the Hilbert function of algbebras with the Lefschetz property. We extend this characterization to algebras…

The variety of exterior powers of linear maps

Winfried Bruns, Aldo Conca

Let $K$ be a field and $V$ and $W$ be $K$ -vector spaces of dimension $m$ and $n$ . Let $ϕ$ be the canonical map from $H o m (V, W)$ to $H o m (\land^{t} V, \land^{t} W)$ . We investigate the Z…
