| Jul 13, 2015 at 21:41 | comment | added | Ofir Gorodetsky | Note that if $f(x) \in \mathbb{F}_{p}[x]$ is a non-zero polynomial satisfying $f(x)=f(x+\alpha)$ for some $\alpha \in \mathbb{F}_{p}^{\times}$, then necessarily $\deg f \ge p$: This is because if $r$ is a root of $f$ (over the algebraic closure) then its translates $r+i,i\in \mathbb{F}_{p}$ must also be roots. | |
