| Abstract: | Some characterizations of the m by n matrices A with p(A) = n have signed generalized inverses (where p (A) = n is the term rank of A )were given in 1,2] and a problem about the characterization of the matrices in a special triangular blcck form to have signed generalized inverses was propcsed in 2]. In this paper, we solve several cases of this problem and obtain some further results about matrices having signed generalized inverses. |
