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…

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…

Convergence results for a coarsening model using global linearization

Th. Gallay, A. Mielke

We study a coarsening model describing the dynamics of interfaces in the one-dimensional Allen-Cahn equation. Given a partition of the real line into intervals of length greater th…

The ends of manifolds with bounded geometry, linear growth and finite filling area

Louis Funar, Renata Grimaldi

We prove that simply connected open Riemannian manifolds of bounded geometry, linear growth and sublinear filling growth (e.g. finite filling area) are simply connected at infinity…
