Scaling and density of states of fractal lattices from a generating function point of view

Abstract
It is shown that the analogy between the free energy in critical phenomena and the complex generating function allows one to exploit well known position-space renormalization group techniques to easily derive scaling properties as well as the exact density of states for electronic or vibrational problems on fractal lattices. Certain self-similar lattices whose spectral dimension d can be larger or less than 2 are also studied
