Abstract

It follows from Chap. 1 that the six important kinds of generalized inverse: the M-P inverse A†, the weighted M-P inverse A†MN, the group inverse Ag, the Drazin inverse Ad, the Bott-Duffin inverse (Formula Presented) and the generalized Bott-Duffin inverse (Formula Presented) are all the generalized inverse (Formula Presented), which is the {2} -inverse of A with the prescribed range T and null space S.
