Sharp bounds for symmetric and asymmetric Diophantine approximation

Number Theory 2009-08-25 v2

Abstract

In 2004, J.C. Tong found bounds for the approximation quality of a regular continued fraction convergent of a rational number, expressed in bounds for both the previous and next approximation. We sharpen his results with a geometric method and give both sharp upper and lower bounds. We also calculate the asymptotic frequency that these bounds occur.
