Singular values and maximum rank minors of generalized inverses
Ravindra B. Bapat, Adi-Ben Israel · Linear and Multilinear Algebra · 1995
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 Awith minimal volume.
