Résumé

Given a large prime number $p$ and a rational function $r (X)$ defined over $𝔽_{p} = ℤ / p ℤ$ , we investigate the size of the set $\{x \in 𝔽_{p} : \tilde{r} (x) > \tilde{r} (x + 1)$ , where $\tilde{r} (x)$ and $\tilde{r} (x + 1)$ denote the least positive representatives of $r (x)$ and $r (x + 1)$ in $ℤ$ modulo $p ℤ$ .

Étant donnés un grand nombre premier $p$ et une fonction rationnelle $r (X)$ définie sur $𝔽_{p} = ℤ / p ℤ$ , on évalue la grandeur de l’ensemble $\{x \in 𝔽_{p} : \tilde{r} (x) > \tilde{r} (x + 1)\}$ , où $\tilde{r} (x)$ et $\tilde{r} (x + 1)$ sont les plus petits représentants de $r (x)$ et $r (x + 1)$ dans $ℤ$ modulo $p ℤ$ .
