On Varieties of Almost Minimal Degree I : Secant Loci of Rational Normal Scrolls
To provide a geometrical description of the classification theory and the structure theory of varieties of almost minimal degree, that is of non-degenerate irreducible projective varieties whose degree exceeds the codimension by precisely 2, a natural approach is to investigate simple projections of varieties of minimal degree. Let X̃ ⊂ P K be a variety of minimal degree and of codimension at le...
متن کاملMosaics of Japanese Picture Scrolls
We propose scveral new techniques for mosaic-ing images of Japanese picture scrolls. Previous methods cannot accurately stitch these images, because they are too wide. To solve this problem , we propose three techniques that can stitch without any seams. The first technique adjusts its height of each image in advance. The second technique uses planar projective transformation among three images...
متن کاملScrolls and Hyperbolicity
Using degeneration to scrolls, we give an easy proof of non–existence of curves of low genera on general surfaces in P of degree d ≥ 5. We show, along the same lines, boundedness of families of curves of small enough genera on general surfaces in P. We also show that there exist Kobayashi hyperbolic surfaces in P of degree d = 7 (a result so far unknown), and give a new construction of such sur...
متن کاملThe Herculaneum Scrolls
Introduction In 1752 antiquity hunters were tunneling down into a large villa on a hill overlooking Herculaneum and the Bay of Naples when they made the discovery of manuscripts. This villa probably once belonged to the wealthy Roman aristocrat Lucius Calpurnius Piso Caesoninus, a well-known Roman politician, who was a patron of Epicurean philosophers. The villa was lost from history in A.D. 79...
متن کاملClassification of Elliptic Line Scrolls
Introduction: Through this paper, a geometrically ruled surface, or simply a ruled surface, will be a P-bundle over a smooth curve X of genus g. It will be denoted by π : S = P(E0)−→X and we will follow the notation and terminology of R. Hartshorne’s book [3], V, Section 2. We will suppose that E0 is a normalized sheaf and X0 is the section of minimum self-intersection that corresponds to the s...
