Quantum ergodicity on the Bruhat-Tits building for $\text{PGL}(3,F)$ in the Benjamini-Schramm limit

Carsten Peterson

We study joint eigenfunctions of the spherical Hecke algebra acting on $L^2({\Gamma }_n\backslash G/K)$ where $G=\text{PGL}(3,F)$ with $F$ a non-archimedean local field of arbitrary…
