The distribution of $αp$ modulo one in real quadratic function fields

Source abstract

Matomäki proved that if $α\in\R$ is irrational, then there are infinitely many primes $p$ such that $|α-a/p|\le p^{-4/3+\varepsilon}$ for a suitable integer $a$. In \cite{BaMo}, Baier and the author established analogues of this result for $\F_q(T)$ and its imaginary quadratic extensions. In this paper, we extend it to all real quadratic extensions of $\F_q(T)$.
