Surjectivity of Gaussian Maps for Curves on Enriques Surfaces

چکیده
Making suitable generalizations of known results we prove some general facts about Gaussian maps. The above are then used, in the second part of the article, to give a set of conditions that insure the surjectivity of Gaussian maps for curves on Enriques surfaces. To do this we also solve a problem of independent interest: a tetragonal curve of genus g ≥ 7 lying on an Enriques surface and general in its linear system, cannot be, in its canonical embedding, a quadric section of a surface of degree g − 1 in P.

Surjectivity of Gaussian maps for curves on Enriques surfaces

These facts are then used, in the second part of the article, to give a set of conditions that insure the surjectivity of Gaussian maps for curves on Enriques surfaces.

متن کاملOn the Extendability of Projective Surfaces and a Genus Bound for Enriques-fano Threefolds
We introduce a new technique, based on Gaussian maps, to study the possibility, for a given surface, to lie on a threefold as a very ample divisor with given normal bundle. We give several applications, among which one to surfaces of general type and another one to Enriques surfaces. For the latter we prove that any threefold (with no assumption on its singularities) having as hyperplane sectio...
متن کاملA Sharp Vanishing Theorem for Line Bundles on K3 or Enriques Surfaces
Let L be a line bundle on a K3 or Enriques surface. We give a vanishing theorem for H(L) that, unlike most vanishing theorems, gives necessary and sufficient geometrical conditions for the vanishing. This result is essential in our study of BrillNoether theory of curves on Enriques surfaces [KL1] and of Enriques-Fano threefolds [KLM].
متن کاملClassification of Complex Algebraic Surfaces
In this note we present the classical Enriques’ classification theorem for complex algebraic surfaces. We’ll recall basic facts about the theory of complex surfaces (structure theorems for birational maps), and discuss (using a modern (=Mori) approach) some important results like the Castelnuovo’s rationality criterion and the classification of minimal ruled surfaces. Finally, after the descrip...
متن کاملOn the Corank of Gaussian Maps for General Embedded K3 Surfaces
Let Sg be a general prime K3 surface in IP g of genus g ≥ 3 or a general double cover of IP 2 ramified along a sextic curve for g = 2 and Si,g its ith Veronese embedding. In this article we compute the corank of the Gaussian map ΦOSi,g (1) : ∧2 H(Si,g,OSi,g(1)) → H (Si,g,Ω 1 Si,g (2)) for i ≥ 2, g ≥ 2 and i = 1, g ≥ 17. The main idea is to reduce the surjectivity of ΦOSi,g (1) to an application...
