Simplicial ramified covering maps
"... Abstract In this paper we define the concept of a ramified covering map in the category of simplicial sets and we show that it has properties analogous to those of the topological ramified covering maps. We show that the geometric realization of a simplicial ramified covering map is a topological ..."

COMPUTATION OF HIGHLY RAMIFIED COVERINGS
, 2009
"... Abstract. An almost Belyi covering is an algebraic covering of the projective line, such that all ramified points except one simple ramified point lie above a set of 3 points of the projective line. In general, there are 1dimensional families of these coverings with a fixed ramification pattern. (T ..."

The transfer for ramified covering Gmaps
, 2009
"... Abstract Let G be a finite group. The main objective of this paper is to study ramified covering Gmaps and to construct a transfer for them in BredonIllman equivariant homology with coefficients in a homological Mackey functor M. We show that this transfer has the usual properties of a transfer. ..."

The number of ramified covering of the sphere by Riemann surface
, 1999
"... Interpreting the number of ramified covering of the sphere by Riemann surface as the relative GromovWitten invariants and applying a gluing formula, we derive a recursive formula for the number of ramified covering of the sphere by Riemann surface with any genus, with elementary branch points and p ..."

Families of wildly ramified covers of curves
 Amer. J. Math
, 2001
"... In this paper, I investigate wildly ramified GGalois covers of curves φ: Y → P 1 k branched at exactly one point over an algebraically closed field k of characteristic p. I answer a question of M. Raynaud by showing that proper families of such covers of a twisted projective line are isotrivial. Th ..."

Wildly ramified covers with large genus
, 2005
"... We study wildly ramified GGalois covers φ: Y → X branched at B (defined over an algebraically closed field of characteristic p). We show that curves Y of arbitrarily high genus occur for such covers even when G, X, B and the inertia groups are fixed. The proof relies on a Galois action on covers of ..."

CONDUCTORS OF WILDLY RAMIFIED COVERS, III
 PACIFIC JOURNAL OF MATHEMATICS VOL. 211, NO. 1, 2003

"... Consider a wildly ramified GGalois cover of curves φ: Y → X branched at only one point over an algebraically closed field k of characteristic p. In this paper, given G such that the Sylow psubgroups of G have order p, I show it is possible to deform φ to increase the conductor at a wild ramificati ..."
