Abstract
Let be a locally symmetric space defined by a simple Chevalley group and a congruence subgroup of . In this generality, the Weyl law for was proved by Lindenstrauss--Venkatesh. In the case where is simply connected, we sharpen their result by giving a power saving estimate for the remainder term.
