Unitarily invariant norm inequalities for functions of accretive-dissipative \(2\times 2\) block matrices
The authors establish several unitarily invariant norm inequalities for accretive-dissipative matrices. They explore some inequalities that involve the accretive-dissipative matrices comparing a block matrix with its off diagonal entries. Their results generalize those of \textit{I. H. Gumus} et al. [Linear Algebra Appl. 528, 76--93 (2017; Zbl 1398.15020)].
