Formal deformation of curves with group scheme action
Stefan Wewers
We study equivariant deformations of singular curves with an action of a finite flat group scheme, using a simplified version of Illusie's equivariant cotangent complex. We apply t…

Stable reduction of modular curves
Irene Ingeborg Bouw, Stefan Wewers
We determine the stable reduction at of all three point covers of the projective line with Galois group . As a special case, we recover the results of Deligne an…

Three point covers with bad reduction
Stefan Wewers
We study Galois covers of the projective line branched at three points with bad reduction to characteristic p, under the condition that p exactly divides the order of the Galois gr…
