Global Properties of Eigenvalues of Parametric Rank One Perturbations for Unstructured and Structured Matrices II
André C. M. Ran, Michał Wojtylak · Complex Analysis and Operator Theory · 2022
Abstract We present in this note a correction to Theorem 17 in Ran and Wojtylak (Compl. Anal. Oper. Theory 15:44, 2021) and sharpen the estimates for eigenvalues of parametric rank one perturbations given in that theorem.
