Abstract

Closed subgroups of the group of isometries of the regular tree \treeq\treeq that fix an end of the tree and are vertex-transitive are shown to correspond, on one hand, to self-replicating groups acting on rooted trees and, on the other hand, to elements of totally disconnected, locally compact groups having positive scale.
