Brill-Noether theory and non-special scrolls
A. Calabri, C. Ciliberto, F. Flamini +1
In this paper we study the Brill-Noether theory of sub-line bundles of a general, stable rank-two vector bundle on a curve C with general moduli. We relate this theory to the geome…
Non-special scrolls with general moduli
Alberto Calabri, Ciro Ciliberto, Flaminio Flamini +1
In this paper we study smooth, non-special scrolls S of degree d, genus g, with general moduli. In particular, we study the scheme of unisecant curves of a given degree on S. Our a…
Surfaces with K^2<3χand finite fundamental group
Ciro Ciliberto, Margarida Mendes Lopes, Rita Pardini
In this paper we continue the study of algebraic fundamentale group of minimal surfaces of general type S satisfying K_S^2<3χ(S). We show that, if K_S^2= 3χ(S)-1 and the algebraic…
Andreotti-Mayer loci and the Schottky problem
Ciro Ciliberto, Gerard van der Geer
We prove a lower bound for the codimension of the Andreotti-Mayer locus N_{g,1} and show that the lower bound is reached only for the hyperelliptic locus in genus 4 and the Jacobia…
