Littlewood's estimates for L‐functions in the hyperelliptic ensemble

We investigate the analogs of certain classical estimates of Littlewood for the Riemann zeta-function in the context of quadratic Dirichlet (Formula presented.) -functions over function fields. In some situations, we are actually able to establish finer results in the function field setup than what is currently known in the original number field setup, and this leads us to an educated guess on what could happen for the Riemann zeta-function in such situations. Fourier analysis techniques play an important role in our approach.
