On the Proportion of Coprime Fractions in Number Fields

Number Theory 2024-03-28 v2

Abstract

In this paper we determine the asymptotic density of coprime fractions in those of the reduced fractions of number fields. When ordered by norms of denominators, we count a fraction as soon as it ``appears'' for the first time and no later. The natural density of coprime fractions in the set of reduced fractions may then be computed using well-known facts about Hecke LL-functions. Furthermore, we draw some connections to the modular group and Heegner points.
