The Multilinear Rank and Core of Trifocal Grassmann Tensors
Marina Bertolini, Gian Mario Besana, Gilberto Bini +1
Closed formulas for the multilinear rank of trifocal Grassmann tensors are obtained. An alternative process to the standard HOSVD is introduced for the computation of the core of t…
The Rank of Trifocal Grassmann Tensors
Marina Bertolini, Gian Mario Besana, Gilberto Bini +1
Grassmann tensors arise from classical problems of scene reconstruction in computer vision. Trifocal Grassmann tensors, related to three projections from a projective space of dime…
Matrices dropping rank in codimension one and critical loci in computer vision
Marina Bertolini, GianMario Besana, Roberto Notari +1
Critical loci for projective reconstruction from three views in four dimensional projective space are defined by an ideal generated by maximal minors of suitable matri…
On families of rank-2 uniform bundles on Hirzebruch surfaces and Hilbert schemes of their scrolls
Gian Mario Besana, Maria Lucia Fania, Flaminio Flamini
Several families of rank-two vector bundles on Hirzebruch surfaces are shown to consist of all very ample, uniform bundles. Under suitable numerical assumptions, the projectivizati…
Hilbert scheme of some threefold scrolls over the Hirzebruch surface F_1
Gian Mario Besana, Maria Lucia Fania, Flaminio Flamini
Hilbert schemes of suitable smooth, projective manifolds of low degree which are 3-fold scrolls over the Hirzebruch surface F_1 are studied. An irreducible component of the Hilbert…
Criteria for very ampleness of rank two vector bundles over ruled surfaces
Alberto Alzati, GianMario Besana
Very ampleness criteria for rank 2 vector bundles over smooth, ruled surfaces over rational and elliptic curves are given. The criteria are then used to settle open existence quest…
