Eigenvalue inequalities for positive block matrices with the inradius of the numerical range

Jean-Christophe Bourin, Eun-Young Lee

We prove some eigenvalue inequalities for positive semidefinite matrices partitioned into four blocks. The inradius of the numerical range of the off-diagonal block contributes to…
