Stabilizers for nondegenerate matrices of boundary format and Steiner bundles

Carla Dionisi

In this paper nondegenerate multidimensional matrices of boundary format in $V_{0} \otimes ... \otimes V_{p}$ are investigated by their link with Steiner vector bundles on product of p…

Grassmann defectivity à la Terracini

Carla Dionisi, Claudio Fontanari

This work is a modern revisitation of a classical paper by Alessandro Terracini, going back to 1915, which suggests an elementary but powerful method for studing Grassmann defectiv…

The Binet-Cauchy Theorem for the Hyperdeterminant of boundary format multidimensional Matrices

Carla Dionisi, Giorgio Ottaviani

Let $A$ , $B$ be multidimensional matrices of boundary format respectively $\prod_{i = 0}^{p} (k_{i} + 1)$ , $\prod_{j = 0}^{q} (l_{j} + 1)$ . Assume that $k_{p} = l_{0}$ so that the convolution $A * B$ is…

Minimal resolution of general stable vector bundles on $\PP^2$

Carla Dionisi, Marco Maggesi

We study the general elements of the moduli spaces (\MM_{\PP^2} (r, c_1, c_2) ) of stable holomorphic vector bundle on $\PP^2$ and their minimal free resolution. Incidentally, a qu…
