Quantum Ergodicity for compact quotients of ${\mathrm{SL}}_d(\mathbb{R})/\mathrm{SO}(d)$ in the Benjamini-Schramm limit

Farrell Brumley, Jasmin Matz

We study the limiting behavior of Maass forms on Benjamini-Schramm convergent sequences of compact quotients of ${\mathrm{SL}}_d(\mathbb{R})/\mathrm{SO}(d)$, $d\ge 3$, whose spectral param…
