The density conjecture for principal congruence subgroups

Edgar Assing, Valentin Blomer

Published 2022-04-19Version 1

We prove Sarnak's density conjecture for the principal congruence subgroup of SL_n(Z) of squarefree level and discuss various arithmetic applications. The ingredients include new bounds for local Whittaker functions and Kloosterman sums.
