Convergence of vectorial continued fractions related to the spectral seminorm. (English) Zbl 1160.46032
Summary: We show that the spectral seminorm is useful to study convergence or divergence of vectorial continued fractions in Banach algebras because such convergence or divergence is related to a spectral property.
