Abstract

Let λ\lambda denote the Liouville function for function fields. We prove that for a fixed qq, given hNh \ll \sqrt{N} and h(N)h(N) \to \infty arbitrarily slowly as NN \to \infty, then \begin{equation*} \frac{1}{q^N}\sum_{G_0 \in \mathcal{M}_N}|\sum_{G \in \mathcal{I}_{h}(G_0)}\lambda(G)|^2 \ll_q \frac{N^5}{h^2}q^{h}. \end{equation*} The proof follows a similar method of an analogous case in the integer setting developed by Chinis, adapting methods originally developed by Matom\"aki and Radziwi{\l}{\l}.
