W. L. Otae, Benard Okelo, Omolo Ongati · Asia Pacific Journal of Mathematics · 2021
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.
