On the cohomology of congruence subgroups of SL_4 (\Z)
arXiv:0905.0401
Abstract
We survey our joint work with Avner Ash and Mark McConnell that computationally investigates the cohomology of conguence subgroups of SL_4 (\Z). This is based on a talk given at the 2009 RIMS conference "Automorphic representations, automorphic L-functions and arithmetic."
