Element-by-Element Schur Complement Approximations for General Nonsymmetric Matrices of Two-by-Two Block Form

2010
We consider element-by-element Schur complement approximations for indefinite and general nonsymmetric matrices of two-by-two block form, as arising in finite element discretized systems of PDEs The paper provides some analysis of the so-obtained approximation and attempts to quantify the quality of the underlying two-by-two matrix splitting in a way ...

Expression of the Drazin and MP-inverse of partitioned matrix and quotient identity of generalized Schur complement

Applied Mathematics and Computation, 2009
Starting with I. Schur there is a considerable literature describing conditions on the blocks of a \(2\times2\) block matrix which enable us to give a simple expression for the inverse matrix, or more generally the Drazin inverse or Moore-Penrose (MP) inverse [see, for example, \textit{X. Sheng} and \textit{C. Chen}, Appl. Math. Comput. 196, No.~1, 174-
