Abstract :
The ith singular value of a transfer matrix, σi(H(jω)), need not be a differential function of ω at frequencies where its multiplicity is greater than one. However, near a local maximum the largest singular value σ1(H(jω)) has a Lipschitz second derivative, but need not have a third derivative. On the basis of this regularity result, the authors obtain a quadratically convergent algorithm for computing the L-norm of a transfer matrix
