Arithmetic quantum unique ergodicity for products of hyperbolic $2$- and $3$-spaces

Zvi Shem-Tov, Lior Silberman

We prove the arithemtic quantum unique ergodicity (AQUE) conjecture for sequences of Hecke--Maass forms on quotients $\hat{I}“\backslash ({\mathbb{H}}^{(2)}{)}^r\times ({\mathbb{H}}^{(3)}{)}^s$…
