Abstract

The paper develops homogeneous-to-inhomogeneous transference through Diophantine exponents. Its best-approximation growth and transference lemmas are used in the fixed-matrix dependence graph.

Metric theory with a fixed matrix

This paper is included only for the following marked statements:

  • Lemma 1 · §2, immediately after equations (4)–(5)A sequence of best-approximation denominators grows at least geometrically. Bugeaud–Laurent give the full pigeonhole proof.
  • Lemma 3 · §3, Transference lemmaTurns a uniform lower bound for the transpose into an inhomogeneous approximation for every shift. Its reproduced proof invokes Cassels, Chapter V, Theorem XVII, Part B.
