Abstract

We discuss some easy statements dealing with linear inhomogeneous Diophantine approximation. Surprisingly, we did not find some of them in the literature. In particular, we prove a precise version of the Kronecker approximation theorem and a related result on coprime approximation.

Notes

  1. Ein Punkt \(\varvec{z} =(z_1,\ldots ,z_d)^\top \in {\mathbb {Z}}^d\) heißt primitiv, wenn die Gleichung \( \textrm{ggT } (z_1,\ldots ,z_d) =1\) gilt.
