A note on unitarily invariant norm inequalities for accretive-dissipative operator matrices
Keywords:
unitarily invariant norms, accretive-dissipative operators, inequalitiesAbstract
In this paper, we present a unitarily invariant norm inequality for accretive-dissipative operator matrices, which is similar to an inequality obtained by Zhang in [J. Math. Anal. Appl. 412 (2014) 564-569]. Examples are provided to show that neither Zhang’s inequality nor our inequality is uniformly better than the other.
