摘要：

This paper is a thorough examination of the connections between the kernels of a "bordered matrix" H(z)= a v* z* v H2 w z w* b and the kernels of the "largest" principal submatrices H1= a v* v H2, H3= H2 w w* b, and H2, (H1, H2, and H3 will usually be not invertible.) These results on bordered matrices may be used in order to construct invertible "extensions" of certain types of "band" matrices. © 1990.
