Weighted Fano Threefold Hypersurfaces
We study birational transformations into elliptic fibrations and birational automorphisms of quasismooth anticanonically embedded weighted Fano 3-fold hypersurfaces with terminal singularities classified by A.R. Iano-Fletcher, J. Johnson, J.Kollár, and M.Reid.
متن کاملBundles over Fano Threefolds of Type V22
An explicit resolution of the diagonal over V22 is given, making use of some observations about instanton bundles with c2 = 3. Different descriptions of V22 are interpreted in terms of mutations of vector bundles.
متن کاملHalphen Pencils on Weighted Fano Threefold Hypersurfaces
We classify all pencils on a general weighted hypersurface of degree ∑ 4 i=1 ai in P(1, a1, a2, a3, a4) whose general members are surfaces of Kodaira dimension zero.
متن کاملThe Fano Surface of the Klein Cubic Threefold
We prove that the Klein cubic threefold F is the only one cubic threefold which has an order 11 automorphism. We calculate the period lattice of the intermediate Jacobian of F and study its Fano surface S. We compute the set of fibrations of S on a curve of positive genus and the intersection between the fibres of these fibrations. These fibres generate an index 2 sub-group of the Néron-Severi ...
متن کاملAcm Bundles on a General Quintic Threefold
We give a partial positive answer to a conjecture of Tyurin ([28]). Indeed we prove that on a general quintic hypersurface of P every arithmetically Cohen–Macaulay rank 2 vector bundle is infinitesimally rigid.
