$p$-adic Hurwitz numbers

Algebraic Geometry 2008-06-05 v2

Abstract

We introduce stable tropical curves and use these to count covers of the pp-adic projective line of fixed degree and ramification types by Mumford curves in terms of tropical Hurwitz numbers. Our counts depend on the branch loci of the covers.
