A Note on Generalized Inverses and a Block-Rank Equation
نویسنده
چکیده
In this paper we study the rank equation rank [ A B C X ] = rank(A) and find the necessary and sufficient conditions when X = A and X = A are the solutions of that equation. In both cases we give a explicit form of matrices B and C. Department of Mathematics, Faculty of Sciences and Mathematics, University of Nǐs P.O.

Forms of Generalized Inverses of Row Block Matrices
Given a row block matrix [A, B ], this paper investigates the relations between the generalized inverse [A, B ]− and the column block matrix [ A− B− ] consisting of two generalized inverses A− and B−. The first step of the investigation is to establish a formula for the minimal rank of the difference [A, B ]− − [ A− B− ] , the second step is to find a necessary and sufficient condition for [A, ...

متن کاملSingular Values and Maximum Rank Minors of Generalized Inverses
Singular values and maximum rank minors of generalized inverses are studied. Proportionality of maximum rank minors is explained in terms of space equivalence. The Moore–Penrose inverse A† is characterized as the {1}–inverse of A with minimal volume.
متن کاملRank Equalities Related to Generalized Inverses of Matrices and Their Applications
This paper is divided into two parts. In the first part, we develop a general method for expressing ranks of matrix expressions that involve Moore-Penrose inverses, group inverses, Drazin inverses, as well as weighted Moore-Penrose inverses of matrices. Through this method we establish a variety of valuable rank equalities related to generalized inverses of matrices mentioned above. Using them,...
