| Abstract: | Several norm equalities and inequalities for operator matrices are proved in this paper. These results, which depend on the structure of circulant and skew circulant operator matrices, include pinching type inequalities for weakly unitarily invariant norms. |
| Keywords: | Norm equality Norm inequality Operator matrix Circulant operator matrix Skew circulant operator matrix Weakly unitarily invariant norm Usual operator norm Schatten p-norm |
