Linear stable range for homology of congruence subgroups via FI-modules
arXiv:1712.00890
Abstract
We answer positively a question of Church, Miller, Nagpal and Reinhold on existence of a linear bound on the presentation degree of the homology of a complex of FI-modules. This implies a linear stable range for the homology of congruence subgroups of general linear groups.
