Fourth power moment of coefficients of automorphic L-functions for GL(m)
Keyword(s):
AbstractLet π be a unitary cuspidal automorphic representation for {\mathrm{GL}_{m}(\mathbb{A}_{\mathbb{Q}})}, and let {L(s,\pi)} be the automorphic L-function attached to π, which has a Dirichlet series expression in the half-plane {\Re s>1}, i.e.L(s,\pi)=\sum_{n=1}^{\infty}\frac{\lambda_{\pi}(n)}{n^{s}}.In this paper we are interested in the upper bound of the fourth power moment of {\lambda_{\pi}(n)}, i.e. {\sum_{n\leq x}\lambda_{\pi}(n)^{4}}. If {m=2}, we are able to consider the sixteenth power moment of {\lambda_{\pi}(n)}. As an application, we consider the lower bound of {\sum_{n\leq x}\lvert\lambda_{\pi}(n)\rvert}, which improves previous results.
