Automorphic tensor products and cuspidal cohomology of the ${\mathrm{GL}}_4$

Chandrasheel Bhagwat, Sudipa Mondal

In this article, we establish an asymptotic lower bound estimate on the contribution of cuspidal automorphic representations of ${\mathrm{GL}}_4({\mathbb{A}}_{\mathbb{Q}})$ to cuspidal coho…
