abstract = {For any real number {\$}x \in [0,1){\$}, we denote by {\$}q{\_}n(x){\$} the denominator of
the {\$}n{\$}-th convergent of the continued fraction expansion of {\$}x{\$} {\$}(n \in
\mathbb{\{}N{\}}){\$}. It is well-known that the Lebesgue measure of the set of points
{\$}x \in [0,1){\$} for which {\$}\log q{\_}n(x)/n{\$} deviates away from {\$}\pi^2/(12\log2){\$}
decays to zero as {\$}n{\$} tends to infinity. In this paper, we study the rate of
this decay by giving an upper bound and a lower bound. What is interesting is
that the upper bound is closely related to the Hausdorff dimensions of the
level sets for {\$}\log q{\_}n(x)/n{\$}. As a consequence, we obtain a large deviation
type result for {\$}\log q{\_}n(x)/n{\$}, which indicates that the rate of this decay is
exponential.},
