Spectral and Boundedness Radii in Locally Convex Algebras
Abdellah El Kinani, Lahbib Oubbi, M. Oudadess · Georgian Mathematical Journal · 1998
Abstract. Connections between the spectral radius and the radius of boundedness are studied. Different characterizations of algebras (Q-property, strong saquentiality) are given in terms of these radii. Examples and applications are also provided.
