摘要

We study analytic properties of the representation zeta functions of arithmetic groups of type \(\textsf{A}_2\) A 2 , such as \(\textsf{SL}_3(\mathbb {Z})\) SL 3 ( Z ) . In particular, we uncover further poles of these functions and determine a natural boundary for their meromorphic continuation beyond their abscissa of convergence. We analyse both the number field and function field case.
