2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/75419We present examples of Maass forms on Hecke congruence groups, giving low eigenvalues on $Γ_0(p)$ for small prime $p$, and the first 1000 eigenvalues for $Γ_0(11)$. We also present calculations of the $L$-functions associated to the Maass forms and make comparisons to the predictions from random matrix theory.14 pages, 9 figuresNumber Theory11M26; 11F11Maass forms and their $L$-functionstext
