The disc separation and the eigenvalue distribution of the Schur complement of nonstrictly diagonally dominant matrices
Abstract The result on the Geršgorin disc separation from the origin for strictly diagonally dominant matrices and their Schur complements in (Liu and Zhang in SIAM J. Matrix Anal. Appl. 27(3):665-674, 2005) is extended to nonstrictly diagonally dominant matrices and their Schur complements, showing...
