摘要

En 中文
In this paper, we study the idempotency of the generalized Schur complement on generalized inverse A A dagger s, together with other familiar generalized inverses such as A(M,N)(dagger) A(dagger) A(d) and A(g), defined from a partitioned idempotent matrix, which is a complementarity of (Jerzy K. Baksalary, Oskar Maria Baksalary, Tomasz Szulc, Properties of Schur complements in partitioned idempotent matrices, Lin. Alg. Appl. 379 (2004) 303-318; D.V. Ouellette, Schur complememnts and statistics, Lin. Alg. Appl. 36 (1981) 187-295]. (C) 2006 Elsevier Inc. All rights reserved.
