Notions of Norm-Attainability and Orthogonality in Banach Spaces

2021 · Asia Pacific Journal of Mathematics

. New notions of norm-attainability and orthogonality are given in this paper. We first consider Range-Kernel orthogonality in norm-attainable classes then we characterize orthogonality conditions for Jordan elementary operators in a Banach space setting.
