Quantitative Chevalley-Weil theorem for curves

Number Theory 2012-11-12 v4 Algebraic Geometry

Abstract

The classical Chevalley-Weil theorem asserts that for an \'etale covering of projective varieties over a number field K, the discriminant of the field of definition of the fiber over a K-rational point is uniformly bounded. We obtain a fully explicit version of this theorem in dimension 1.
