Variation of parabolic cohomology and Poincare duality

Michael Dettweiler, Stefan Wewers

We continue our study of the variation of parabolic cohomology (math.AG/0310139) and derive an exact formula for the underlying Poincare duality. As an illustration of our methods,…

The local lifting problem for dihedral groups

Irene I. Bouw, Stefan Wewers

Let $G = D_{p}$ be the dihedral group of order $2 p$ , where $p$ is an odd prime. Let $k$ an algebraically closed field of characteristic $p$ . We show that any action of $G$ on the ring…

Alternating groups as monodromy groups in positive characteristic

Irene I. Bouw, Stefan Wewers

Let $X$ be a generic curve of genus $g$ defined over an algebraically closed field $k$ of characteristic $p \geq 0$ . We show that for $n$ sufficiently large there exists a tame rati…

Stable reduction of three point covers

Stefan Wewers

This note gives a survey on some results related to the stable reduction of three point covers, which were the topic of my talk at the {\em Journées Arithmetiques} 2003 in Graz.
