Title : Density of growth rates of subgroups of the free group.
Abstract:
We prove that the set of growth-rates of subgroups of a rank r free group is dense in[1,2r−1]. Our main technical contribution is a concentration result for the leading eigenvalue of the non-backtracking matrix in the configuration model.
