摘要：

The central gap in the density of states and the localization of states on a Penrose lattice are investigated within a tight-binding model for the vertex problem. The results show that the gap is a consequence of frustration. There are surface states within the gap in a finite lattice. The correlation between the appearance of the gap and the localization of states is also studied.
