The paper is concerned with the determination of the inertia triple for certain partitioned Hermitian matrices. We make repeated use of the Sylvester-Hermite theorem that the inertia of an Hermitian matrix remains invariant under a cogredient transformation. That is, if K P HP, where P is a non-singular matrix and H is Hermitian, then K is also Hermitian, and In K In H. Author
