Gershgorin circle theorem bounds

Webk of Theorem (1) is stronger than what the Gershgorin circle theorem[15, 45] gives in this case: the circle theorem provides in every interval [0;2d k] at least one eigenvalue lof K. It does not need to be the k’th one. In the Kirchho case, where the Gershgorin circles are nested, 0 is always in the spectrum. Theorem (1) gives more information.
