Abstract

In 1974, M. B. Nathanson proved that every irrational number α represented by a simple continued fraction with infinitely many elements greater than or equal to k is approximable by an infinite number of rational numbers p/q satisfying |α-p/q|<1/(√(k2+4)q2). In this paper we refine this result.
