On the characterization of scalar type spectral operators
P. A. Cojuhari, A. M. Gomilko (2008)
Studia Mathematica
Similarity:
The paper is concerned with conditions guaranteeing that a bounded operator in a reflexive Banach space is a scalar type spectral operator. The cases where the spectrum of the operator lies on the real axis and on the unit circle are studied separately.
