2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/59220We study the degeneracy loci of general bundle morphisms from the direct sum of m copies of the structural sheaf on $P^n$ to $Ω(2)$, also from the point of view of the classical geometrical interpretation of the sections of $Ω(2)$ as linear line complexes. We consider in particular the case of $P^5$ with m=2, 3. For n=5 and m=3 we give an explicit description of the Hilbert scheme H of elliptic normal scrolls in $P^5$, by defining a natural rational map from the Grassmannian G(2,14) to H, which results to be dominant with general fibre of degree four.17 pages, 1 figure, to be published in Geometriae DedicataAlgebraic Geometry14F05, 14H52, 14J10text
