Systolic growth of linear groups
arXiv:1408.5837 · doi:10.1090/proc12747
Abstract
We prove that the residual girth of any finitely generated linear group is at most exponential. This means that the smallest finite quotient in which the -ball injects has at most exponential size. If the group is also not virtually nilpotent, it follows that the residual girth is precisely exponential.
