Adjoint Line Bundles and Syzygies of Projective Varieties
Let X be a smooth projective variety and let K be the canonical divisor of X. In this paper, we study embeddings of X given by adjoint line bundles K ⊗ L, where L is an ample invertible sheaf. When X is a regular surface, we obtain a numerical criterion for K ⊗ L to have property Np. In particular, we prove Mukai’s conjecture for regular anticanonical surfaces. When X is a regular variety of ar...
متن کاملLine Bundles on Projective Spaces Preliminary Draft
0.1. Notations and Conventions. During this note, we will fix a base field k (e.g. the complex numbers C). The multiplicative group of the field k will be denoted by Gm. All the vector spaces considered will be finite dimensional vector spaces over the field k. For a given vector space V of dimension≥ 1, we will denote the dual vector space, the projective space parameterizing 1-dimensional sub...
متن کاملA note on deformations of bundles on the projective line
We determine in an elementary fashion the dimension of the space of innni-tesimal deformations of an arbitrary vector bundle on the complex projective line, showing its dependence on the precise form of the decomposition of the bundle under consideration.
متن کاملVery ample line bundles on blown - up projective varieties
Let X be the blowing up of the smooth projective variety V . Here we study when a line bundle M on X is very ample and, if very ample, the k-very ampleness of the induced embedding of X .
متن کاملA Remark on the Jet Bundles over the Projective Line
Let X be a Riemann surface equipped with a projective structure (i.e., a covering by coordinate charts such that the transition functions are of the form z 7−→ (az + b)/(cz + d)). Let L be a line bundle on X such that L = TX . Let J (L) −→ X denote the jet bundle of order m for the line bundle L. For i ≥ j, there is a natural restriction homomorphism from J (L) onto J (L). We prove that for any...
