Journal ArticleDOI

Characterization of Birkhoff–James orthogonality

TL;DR: The Birkhoff-James orthogonality as discussed by the authors is a generalization of Hilbert space orthogons to Banach spaces, and it can be seen as a special case of the Hilbert C∗-algebra.
Journal ArticleDOI

Norm inequalities related to the matrix geometric mean

TL;DR: Inequalities for norms of different versions of the geometric mean of two positive definite matrices are presented in this paper, where the norm is defined as a function of the positive definite matrix.
Journal ArticleDOI

Orthogonality to matrix subspaces, and a distance formula

TL;DR: A necessary and sufficient condition for a matrix A to be Birkhoff-James orthogonal to any subspace W of M n (C ) is given in this paper.
Journal ArticleDOI

Orthogonality of matrices in the Ky Fan k-norms

TL;DR: In this article, necessary and sufficient conditions for a matrix A to be Birkhoff-James orthogonal to another matrix B in the Ky Fan k-norms were obtained.
Journal ArticleDOI

Derivatives of tensor powers and their norms

TL;DR: In this paper, it was shown that a positive m-linear map between C � -algebras attains its norm at the m-tuple (I, I,...,I).
