We will discuss Cauchy’s interlacing inequalities for the eigenvalues of a Hermitian matrix and its principle submatrices. We will discuss their relatives, for example, interlacing inequalities for the singular values of a complex matrix and its submatrices. We seek a possible unified treatment for different interlacing inequalities in the context of semisimple Lie algebras.
