Unramified cohomology of degree 3 and Noether's problem

Emmanuel Peyre

Let be a finite group and be a faithful representation of over {\bf C}. The group acts on the field of rational functions . The aim of this paper is t…

Normal affine surfaces with -actions

Hubert Flenner, Mikhail Zaidenberg

A classification of normal affine surfaces admitting a -action was given in the work of Białynicki-Birula, Fieseler and L. Kaup, Orlik and Wagreich, Rynes and others. We p…

Chromatic properties of generic planar configurations of points

Roland Bacher, David Garber

We study the Orchard relation for generic configurations of points in the plane (also called order types). We introduce infinitesimally-close points and analyse the relation of thi…

Accidental parabolics and relatively hyperbolic groups

Francois Dahmani

By constructing, in the relative case, objects analoguous to Rips and Sela's canonical representatives, we prove that the set of images by morphisms without accidental parabolic, o…

Witten's top Chern class via K-theory

Alessandro Chiodo

The Witten top Chern class is the crucial cohomology class needed to state a conjecture by Witten relating the Gelfand-Dikii hierarchies to higher spin curves. In math.AG/0011032,…

On a universal mapping class group of genus zero

Louis Funar, Christophe Kapoudjian

The aim of this paper is to introduce a group containing the mapping class groups of all genus zero surfaces. Roughly speaking, such a group is intended to be a discrete analogue o…
