On spectral boundedness
Robin Harte
Trinity College
For linear operators between Banach algebras ``spectral boundedness" is derived from ordinary boundedness by substituting spectral radius for norm. The interplay between this concept and some of its near relatives is conspicuous in a result of Curto and Mathieu.
Keywords: spectral boundedness, derivation
