Non-special projectively normal line bundles on general k-gonal curves

E. Ballico (2004)

Annales Polonici Mathematici

Let X be a sufficiently general smooth k-gonal curve of genus g and R ∈ Pic(X) the degree k spanned line bundle. We find an optimal integer z > 0 such that the line bundle $R^{\otimes z}$ is very ample and projectively normal.

Non-supersingular hyperelliptic jacobians

Yuri G. Zarhin (2004)

Bulletin de la Société Mathématique de France

Let $K$ be a field of odd characteristic $p$ , let $f (x)$ be an irreducible separable polynomial of degree $n \geq 5$ with big Galois group (the symmetric group or the alternating group). Let $C$ be the hyperelliptic curve $y^{2} = f (x)$ and $J (C)$ its jacobian. We prove that $J (C)$ does not have nontrivial endomorphisms over an algebraic closure of $K$ if either $n \geq 7$ or $p \neq 3$ .

Normal generation of line bundles on a general $k$ -gonal algebraic curve

Edoardo Ballico, Changho Keem, Seonja Kim (2003)

Bollettino dell'Unione Matematica Italiana

We prove that a very ample special line bundle $L$ of degree $d > (3 g - 1) / 2$ on a general $k$ -gonal curve is normally generated if the degree of the base locus of its dual bundle $K L^{- 1}$ does not exceed $c (k - 2) / 2$ , where $c := d - (3 g - 1) / 2$ .
