Inequalities for Unitarily Invariant Norms

SIAM Journal on Matrix Analysis and Applications, 1998
Let \(A,B,X\) be complex matrices with \(A,B\) positive semidefinite. The author proves the following generalization of the arithmetic-mean inequality due to \textit{R. Bhatia} and \textit{C. Davis} [ibid. 14, No. 1, 132-136 (1993; Zbl 0767.15012]: \[ (2+t)\| A^rXB^{2-r}+A^{2-r}XB^r\| \leq 2\| A^2X+tAXB+XB^2\| \] for arbitrary unitarily invariant norm \

Unitarily invariant norm inequalities for positive semidefinite matrices

Linear Algebra and its Applications, 2022
Let \(M_n(\mathbb{C})\) denote the space of all \(n\times n\) complex matrices. \textit{F. Kittaneh} [J. Funct. Anal. 250, No. 1, 132--143 (2007; Zbl 1131.47009)] proved that if \(A, B, X \in M_n(\mathbb{C})\) such that \(A, B\) are positive semidefinite, then \[ \|| AX-XB |\| \le \Vert X\Vert~\|| A \oplus B |\|, \] where \(\|| \cdot |\|\) denotes the ...
