Classes of operators related to isometries

Classes of operators related to isometries Abstract In this paper, we introduce the classes of analytic extensions of isometric operators and F-quasi-isometric operators. We show that every analytic extension of isometric operator and F-quasi-isometric operator have scalar extensions. Some spectral properties are also presented. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Operator Theory Springer Journals

Abstract

Abstract In this paper, we introduce the classes of analytic extensions of isometric operators and F-quasi-isometric operators. We show that every analytic extension of isometric operator and F-quasi-isometric operator have scalar extensions. Some spectral properties are also presented.
