الوصف: | For a large class of operators on Banach spaces, a natural growth condition is shown to guarantee Bishop’s property (β). For weighted shifts, this result leads to a sufficient condition in terms of the underlying weight se-quence. In the opposite direction, it is shown that every unilateral weighted shift with property (β) has fat local spectra and approximate point spec-trum a circle, while bilateral weighted shifts with property (β) have either fat local spectra or spectrum a circle. A useful new tool is the inner local spectral radius, a counterpart of the standard (outer) local spectral radius. For weighted shifts with Dunford’s property (C), both the inner and outer spectral radii turn out to be constant. |
