NORM ATTAINABILITY OF GENERALIZED FINITE OPERATORS ON C*-ALGEBRA

Abstract

Norm attainability of elementary operators on Hilbert and Banach spaces has been characterized before. However, there is little information on Norm attainability of generalized finite operators on C*-algebra. This paper reports the norm attainability of generalized finite operators on C*-algebra. The approach of Okello 2018 has been used to determine norm attainability. Given two pairs of norm attainable operators A, B, implementing the generalized finite operators|| AX - XB - I || >_ 1 , it then follows that the generalized finite operator is also norm attainable.
