Abstract
With any self-similar action of a finitely generated group of automorphisms of a regular rooted tree can be naturally associated an infinite sequence of finite graphs , where is the Schreier graph of the action of on the -th level of . Moreover, the action of on gives rise to orbital Schreier graphs , . Denoting by the prefix of length of the infinite ray , the rooted graph is then the limit of the sequence of finite rooted graphs in the sense of pointed Gromov-Hausdorff convergence. In this paper, we give a complete classification (up to isomorphism) of the limit graphs associated with the Basilica group acting on the binary tree, in terms of the infinite binary sequence .
