Abstract
We characterize all monic polynomials $f(x) \in \mathbb {Z}[x]$ that have the property that \[f(p) \,|\, f(p^{p}) \quad \ \text {for all sufficiently large primes }p \geq N(f). \] We also give necessary conditions and a sufficient condition for monic polynomials $f(x) \in \mathbb {Z}[x]$ to satisfy $f(p) \,|\, f(p^{p})$ for all primes $p$.
