Abstract EN
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 application, we present new inclusion regions for eigenvalues of the Schur complement of Ostrowski matrix.
In addition, a new upper bound for the infinity norm on the inverse of the Schur complement of Ostrowski matrix is given.
Finally, we give numerical examples to illustrate the theory results.
