Potential density of rational points on the variety of lines of a cubic fourfold
Ekaterina Amerik, Claire Voisin
We prove the potential density of rational points on the variety of lines of a sufficiently general cubic fourfold defined over a number field, where ``sufficiently general'' means…
Formal loops II: A local Riemann-Roch theorem for determinantal gerbes
M. Kapranov, E. Vasserot
If V is a bundle of Tate vector spaces over a base B, its determinantal gerbe has a class C_1(V) in the second cohomology group of the sheaf of invertible functions which can be se…
Fibration de Hitchin et endoscopie
Ngo Bao Chau
We propose a geometric interpretation of the theory of elliptic endoscopy, due to Langlands and Kottwitz, in terms of the Hitchin fibration. As applications, we prove a global anal…
Orbifoldes à premi\ere classe de Chern nulle
Frederic Campana
An orbifold version of Bogomolov decomposition theorem is established for compact Kähler spaces with quotient singularities and first Chern class zero.The proof is a direct adaptat…
Monodromie d'une famille d'hypersurfaces
Ania Otwinowska
I describe the monodromy of smooth hypersurfaces of high degree in a fixed smooth variety containing a fixed subvariety of . The cohomology of in middle degree s…
Sur les varietes de Hodge
Ania Otwinowska
Let be a smooth complex projective variety of dimension , an invertible sufficiently ample sheaf, a smooth hypersurface and a vanishing c…
