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…

Equivariant derived category of a complete symmetric variety

Stéphane Guillermou

Let G be a complex algebraic semi-simple adjoint group and X a smooth complete symmetric G-variety. Let L_i be the irreducible G-equivariant intersection cohomology complexes on X,…

Quelques remarques sur le champ des courbes hyperelliptiques en caracteristique deux

Jose Bertin

Dans cette note on decrit le champ des courbes hyperelliptiques lisses defines sur un corps algebriquement clos de caracteristique deux comme un champ quotient. On en deduit le gro…
