摘要：

We re-examine the conventional idea of determining the nature of the electronic eigenfunctions (extended, critical or localised) of a Fibonacci lattice from a study of the invariant associated with the trace map. We demonstrate that this is insufficient, and a more detailed study of the renormalisation group transformation itself is required to ascertain the nature of the eigenfunctions. Suitable examples are provided.
