On some estimates involving Fourier coefficients of Maass cusp forms
Let [Formula: see text] be a Heckeā€“Maass cusp form for [Formula: see text] with Laplace eigenvalue [Formula: see text] and let [Formula: see text] be its [Formula: see text]th normalized Fourier coefficient. It is proved that, uniformly in [Formula: see text], [Formula: see text] where the implied constant depends only ā€¦
