    One sided Star and Core orthogonality of matrices

    Full text link
    We investigate two one-sided orthogonalities of matrices, the first of which is left (right) ∗*-orthogonality for rectangular matrices and the other is left (right) core-orthogonality of index 11 matrices. We obtain some basic results for these matrices, their canonical forms, and characterizations. Also, relations between left (right) orthogonal matrices and parallel sums are investigated. Finally under these one-sided orthogonalities we explore the conditions of additivity of the Moore-Penrose inverse and the core inverse
