On a certain class of subspectra

Andrzej Sołtysiak (1991)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The aim of this paper is to characterize a class of subspectra for which the geometric spectral radius is the same and depends only upon a commuting $n$ -tuple of elements of a complex Banach algebra. We prove also that all these subspectra have the same capacity.
