The INTEGRAL View of the Galactic Nucleus

A. Goldwurm, G. Belanger, P. Goldoni +15

We present the preliminary results of the observational campaign performed in 2003 to study the Galactic Nucleus with INTEGRAL. The mosaicked images obtained with the IBIS/ISGRI co…

Lissite de la courbe de Hecke de GL(2) aux points Eisenstein critiques

Joel Bellaiche, Gaetan Chenevier

Let p be a prime number and C be the p-adic tame level 1 eigencurve introduced by Coleman-Mazur. We prove that C is smooth at the evil Eisenstein points and we give necessary and s…

Self-similar fragmentations derived from the stable tree II: splitting at nodes

Gregory Marc Miermont

We study a natural fragmentation process of the so-called stable tree introduced by Duquesne and Le Gall, which consists in removing the nodes of the tree according to a certain pr…

Canonical bases of loop algebras via Quot schemes, I

Olivier Schiffmann

We propose a construction of some canonical bases for quantum loop algebras of Kac-Moody algebras. We consider a smooth projective curve X, a group of automorphism G of X such that…

The genealogy of self-similar fragmentations with negative index as a continuum random tree

Benedicte Haas, Gregory Miermont

We encode a certain class of stochastic fragmentation processes, namely self-similar fragmentation processes with a negative index of self-similarity, into a metric family tree whi…
