Lower Bounds on High Moments of Twisted Fourier coefficients of Modular Forms

Peng Gao, Liangyi Zhao

For any large prime , and any real , we prove a lower bound for the following -th moment \begin{equation*} \sum_{\substack{χ\in X_q^*}} \Big| \sum_{n\leq…

Shifted moments of cubic and quartic Dirichlet -functions

Peng Gao, Liangyi Zhao

We establish upper bounds for shifted moments of cubic and quartic Dirichlet -functions under the generalized Riemann hypothesis. As an application, we prove bounds for moments…
