| Popis: |
In this paper, some established properties and results on numerical range and quadratic numerical range of block operator matrices are studied and compared. These results and properties are then applied to compute both ranges for block operator matrices of self-adjoint as well as non-self-adjoint types in the complex Hilbert space. |
