Generalized weight properties of resultants and discriminants, and applications to projective enumerative geometry

Laurent Busé, Thomas Dedieu

The goal of this text is to understand and prove a formula stated by Salmon, which gives the first terms of some Taylor expansion of the discriminant of a plane algebraic curve. Sa…

A note on Severi varieties of nodal curves on Enriques surfaces

C. Ciliberto, T. Dedieu, C. Galati +1

Let $∣ L ∣$ be a linear system on a smooth complex Enriques surface $S$ whose general member is a smooth and irreducible curve of genus $p$ , with $L^{2} > 0$ , and let $V_{∣ L ∣, δ} (S)$ b…

Irreducible unirational and uniruled components of moduli spaces of polarized Enriques surfaces

Ciro Ciliberto, Thomas Dedieu, Concettina Galati +1

We give an explicit description of the irreducible components of the moduli spaces of polarized Enriques surfaces in terms of decompositions of the polarization as an effective sum…

On the irreducibility of Severi varieties on K3 surfaces

Ciro Ciliberto, Thomas Dedieu

Let $(S, L)$ be a polarized $K 3$ surface of genus $p ⩾ 11$ such that $Pic (S) = Z [L]$ , and $δ$ a non-negative integer. We prove that if $p ⩾ 4 δ - 3$ , the…

Wahl maps and extensions of canonical curves and K3 surfaces

Ciro Ciliberto, Thomas Dedieu, Edoardo Sernesi

Let $C$ be a smooth projective curve of genus $g \geq 11$ , non-tetragonal, considered in its canonical embedding in $P^{g - 1}$ . We prove that $C$ is a linear section of an…
