New variants of arithmetic quantum ergodicity

Number Theory 2025-06-26 v2

Abstract

We establish two new variants of arithmetic quantum ergodicity. The first is for self-dual GL2\mathrm{GL}_2 Hecke-Maass newforms over Q\mathbb{Q} as the level and Laplace eigenvalue vary jointly. The second is a nonsplit analogue wherein almost all restrictions of Hilbert (respectively Bianchi) Hecke-Maass cusp forms to the modular surface dissipate as their Laplace eigenvalues grow.
