Abstract

In this paper the conditions under which the weighted generalized inversesA (1,3M), A(1,4N), A M,N Dg andA d,W can be expressed in Banachiewicz-Schur form are considered and some interesting results are established. These results contribute to verify recent results obtained by J. K. Baksalary and G. P. Styan [2] and Y. Wei [15] and these extend their works.
