This exercise relates the singular values of a well-behaved linear operator or matrix to its eigenvalues. (a) Let T be a normal linear operator on an n-dimensional inner product space with eigenvalues λ1, λ2, . . . , λn. Prove that the singular values of T are |λ1| |λ2|, . . . , |λn|. (b) State and prove a result for matrices analogous to (a).
