摘要
A real-space renormalization group (RSRG) scheme is developed to calculate the local Green's functions for electrons in two-dimensional quasi-crystals. The RSRG transformations are derived in terms of the inflation rule of the quasi-crystals. The local electronic densities of states at some key sites are presented, which match the numerical results obtained by other groups for the global electronic energy spectra of the quasi-crystals.
