Résumé
Abstract

On démontre lʼexistence dʼune constante C telle que tout rationnel $\frac{b}{q} \in] 0, 1 [$ , $(b, q) = 1$ , a une représentation comme somme finie $\frac{b}{q} = \sum_{α} \frac{b_{α}}{q_{α}}$ où $\sum_{α} \sum_{i} a_{i} (\frac{b_{α}}{q_{α}}) < C \log q$ et ${a_{i} (x)}$ est la suite des quotients partiels de x.

It is shown that there is an absolute constant C such that any rational $\frac{b}{q} \in] 0, 1 [$ , $(b, q) = 1$ , admits a representation as a finite sum $\frac{b}{q} = \sum_{α} \frac{b_{α}}{q_{α}}$ where $\sum_{α} \sum_{i} a_{i} (\frac{b_{α}}{q_{α}}) < C \log q$ and ${a_{i} (x)}$ denotes the sequence of partial quotients of x.
