Surjectivity of Gaussian maps for curves on Enriques surfaces
A. L. Knutsen, A. F. Lopez
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 condi…

A sharp vanishing theorem for line bundles on K3 or Enriques surfaces
A. L. Knutsen, A. F. Lopez
Let be a line bundle on a K3 or Enriques surface. We give a vanishing theorem for that, unlike most vanishing theorems, gives necessary and sufficient geometrical cond…

On the extendability of projective surfaces and a genus bound for Enriques-Fano threefolds
A. L. Knutsen, A. F. Lopez, R. Muñoz
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…
