Autour d'une surface rationnelle dans

Adrien Dubouloz

Affine surfaces in defined by an equation of the form have been increasingly studied during the past 15 years. Of particular interest is the fact…

Birational transformations of weighted graphs

Hubert Flenner, Shulim Kaliman, Mikhail Zaidenberg

We introduce the notion of a standard weighted graph and show that every weighted graph has an essentially unique standard model. Moreover we classify birational transformations be…

Stable spherical varieties and their moduli

Valery Alexeev, Michel Brion

We introduce a notion of stable spherical variety which includes the spherical varieties under a reductive group and their flat equivariant degenerations. Given any projective…

On covering and quasi-unsplit families of rational curves

L. Bonavero, C. Casagrande, S. Druel

We study extremality properties of covering families of rational curves on projective varieties. Among others, we show that on a normal and Q-factorial projective variety of dimens…

Pfaffian Lines and Vector Bundles on Fano Threefolds of Genus 8

Atanas Iliev, Laurent Manivel

Let X be a general complex Fano threefold of genus 8. We prove that the moduli space of rank two semistable sheaves on X with Chern numbers c_1=1, c_2=6 and c_3=0 is isomorphic to…

Quelques remarques sur la notion de modification affine

Adrien Dubouloz

We construct a global counterpart to the notion of affine modification due to Kaliman and Zaidenberg. This leads to a simple explicit description of the structure of birational aff…
