On sums of Fourier coefficients of cusp forms

TLDR
In this paper, the summatory function of non-holomorphic cusp forms is estimated, where the sum is the Hecke series of a nonholomorphic Cusp form.
Abstract
The summatory function of $t_j(n^2)$ is estimated, where $H_j(s) = \sum_{n=1}^\infty t_j(n)n^{-s}$ is the Hecke series of a non-holomorphic cusp form. The analogous problem of holomorphic cusp forms is also treated.

Spectral Theory of the Riemann Zeta-Function

TL;DR: Motohashi as discussed by the authors showed that the Riemann zeta function is closely bound with automorphic forms and that many results from there can be woven with techniques and ideas from analytic number theory to yield new insights into, and views of, the zeta functions.
