On quadratic irrationals with bounded partial quotients

Number Theory 2016-08-10 v2

Abstract

It is shown that for some explicit constants c>0,A>0c>0, A>0, the asymptotic for the number of positive non-square discriminants D<xD<x with fundamental solution εD<x12+α,0<α<c\varepsilon_D< x^{\frac 12+\alpha}, 0<\alpha <c, remains preserved if we require moreover Q(D)\mathbb Q(\sqrt D) to contain an irrational with partial quotients bounded by AA.
