| Jul 5, 2016 at 7:04 | comment | added | Andreas Thom | I think that it should follow from the answer to mathoverflow.net/questions/54921/… that there exists a sequence of sets $S_n$ (certain level-sets of the probability distribution of the random walk at time $n$), so that any subgroup of infinite index has decaying lower density with respect to $S_n$ - but I am not sure what happens with Cayley balls. | |
