SUMMARY:Anderson transition at 2D growth-rate for the Anderson model on an

DESCRIPTION:An antitree is a discrete graph that is split into countably m
 any shells $S_n$ consisting of finitely many vertices so that all vertices
  in $S_n$ are connected with all vertices in the adjacent shells $S_{n+1}$
  and $S_{n-1}$. We normalize the edges between $S_n$ and $S_{n+1}$ with we
 ights to have a bounded adjacency operator and add an iid random potential
 . We are interested in the case where the number of vertices $# S_n$ in th
 e $n$-th shell grows like $n^a$. In a particular set of energies we obtain
  a transition of the spectral type from pure point to partly s.c. to a.c. 
 spectrum at $a=1$ which corresponds to the growth-rate in 2 dimensions.\n
