Wild monodromy and automorphisms of curves
Claus Lehr, Michel Matignon
Let be a complete discrete valuation ring of mixed characteristic with field of fractions containing the -th roots of unity. This paper is concerned with semi-st…
Problems from the workshop on "Automorphisms of Curves" (Leiden, August, 2004)
I. Bouw, T. Chinburg, G. Cornelissen +7
Contents: Rational functions with given monodromy on generic curves (I. Bouw & S. Wewers); Can deformation rings of group representations not be local complete intersections? (T. C…
An analog to Deuring's criterion for good reduction of elliptic curves
Claus Lehr
In this paper we study the reduction of -cyclic covers of the -adic line ramified at exactly four points. For these covers are elliptic curves and Deuring has given a c…
Automorphisms groups for -cyclic covers of the affine line
Claus Lehr, Michel Matignon
Let be an algebraically closed field of positive characteristic and a -cyclic cover of the projective line ramified in exactly one point. We ar…
