Rigidity of amalgamated product in negative curvature
Gerard Besson, Gilles Courtois, Sylvain Gallot
Let be the fundamental group of a compact n-dimensional riemannian manifold X of sectional curvature bounded above by -1. We suppose that is a free product of its subgroup…
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…
Moment polytopes for symplectic manifolds with monodromy
San Vu Ngoc
A natural way of generalising Hamiltonian toric manifolds is to permit the presence of generic isolated singularities for the moment map. For a class of such ``almost-toric 4-manif…
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…
On the eigenvalues for slowly varying perturbations of a periodic Schrödinger operator
Magali Marx
In this paper, I consider one-dimensional periodic Schr{ö}dinger operators perturbed by a slowly decaying potential. In the adiabatic limit, I give an asymptotic expansion of the e…
