Statistics of genus numbers of cubic fields

Number Theory 2017-01-02 v2

Abstract

We prove that approximately 96.23%96.23\% of cubic fields, ordered by discriminant, have genus number one, and we compute the exact proportion of cubic fields with a given genus number. We also compute the average genus number. Finally, we show that a positive proportion of totally real cubic fields with genus number one fail to be norm-Euclidean.
