The Diagonally Dominant Degree and Disc Separation for the Schur Complement of Ostrowski Matrix
By applying the properties of Schur complement and some inequality techniques, some new estimates of diagonally and doubly diagonally dominant degree of the Schur complement of Ostrowski matrix are obtained, which improve the main results of Liu and Zhang (2005) and Liu et al. (2012). As an applicat...
