Abstract

Let p0, p1 0 and inertia of the matrix Kr is same as that of inertia of the matrix L−r, when r≤0. In this paper, a congruence relation has been established between these matrix families using an upper triangular matrix. Motivated from this, a general characterization for symmetric matrices to be congruent using upper triangular matrix has been provided.
