Abstract

In this article we generalize Borel’s classical approximation results for the regular continued fraction expansion to the α-Rosen fraction expansion, using a geometric method. We use α-Rosen fractions to give a Haas-Series-type result about all possible good approximations for the α for which the Legendre constant is larger than the Hurwitz constant.


Keywords

Rosen fractions, natural extensions, approximation quality.
