vanishing of rank gradient for lattices in higher rank lie groups via cost
abstract:
in 2016 abert, gelander, and nikolov made what they called a provocative conjecture: for lattices in higher-rank simple lie groups, the minimum size of a generating set (rank) is sublinear in the volume. i will discuss our solution to this conjecture. it is a corollary of our main result, where we establish "fixed price one" for a more general class of "higher rank" groups. no familiarity of fixed price or cost is required for the talk. joint work with mikolaj fraczyk and amanda wilkens.
