Spectrum of partial automorphisms of regular rooted tree

Group Theory 2020-06-30 v1

Abstract

We study properties of eigenvalues of a matrix associated with a randomly chosen partial automorphism of a regular rooted tree. We show that asymptotically, as the numbers of levels goes to infinity, the fraction of non-zero eigenvalues converges to zero in probability.
