Even sets of four nodes on rational surfaces
Alberto Calabri, Ciro Ciliberto, Margarida Mendes Lopes
We describe smooth rational projective algebraic surfaces X, over an algebraically closed field of characteristic different from 2, having an even set of four disjoint (-2)-curves…
Varieties with minimal secant degree and linear systems of maximal dimension on surfaces
Ciro Ciliberto, Francesco Russo
In this paper we prove, using a refinement of Terracini's Lemma, a sharp lower bound for the degree of (higher) secant varieties to a given projective variety, which extends the we…
Braid monodromy factorization for a non-prime surface branch curve
M. Amram, C. Ciliberto, R. Miranda +1
This paper is the second in a series. The first one describes pillow degenerations of a surface with genus . In this paper we study the -pillow degeneration of a non…
Canonical map of low codimensional subvarieties
Valentina Beorchia, Ciro Ciliberto, Vincenzo Di Gennaro
Fix integers , and . We prove that for certain projective varieties (e.g. certain possibly singular complete intersections), there are only fi…
