In this paper, we first define some generalized Schur complements, then we study the representation of M–P inverse M1† group inverse M1g and Drazin M1d for the partitioned matrix M1=ABCD. Based on this, we give three kind quotient identities of generalized Schur complement about the partitioned matrix K=ABECDFGHL and develops the results in paper [M. Redivo-Zaglia, Pseudo-Schur complement and their applications, Appl. Num. Math. 50 (2004) 511–519; K. Jbilou, A. Messaoudi, K. Tabaâ, Some Schur complement identities and applications to matrix exatrapolation methods, Linear Algebra Appl. 392 (2004) 195–210]. In the end of the paper, we give the application of these generalized Schur complement in solution of linear equation, and give numerical example to show our results.
