Extremal behavior of divisibility functions [link]Paper  doi  abstract   bibtex   
In this short article, we study the extremal behavior F (n) of divisibility functions D introduced by the first author for finitely generated groups . These functions aim at quantifying residual finiteness and bounds give a measurement of the complexity in verifying a word is non-trivial. We show that finitely generated subgroups of GL(m, K ) for an infinite field K have at most polynomial growth for the function F (n). Consequently, we obtain a dichotomy for the growth rate of log F (n) for finitely generated subgroups of GL(n, C). We also show that if F (n) log log n, then is finite. In contrast, when contains an element of infinite order, log n F (n). We end with a brief discussion of some geometric motivation for this work.
