Abstract

The original version of this paper appeared in Linear Algebra and its Applications, volume 430, pp.34 - 40, 2009. Here we correct a slight gap in the statement and proof of Lemma 3.1 in that paper. We revisit the theorem of Barker, Berman and Plemmons on the existence of a diagonal quadratic Lyapunov function for a stable linear time-invariant (LTI) dynamical system [1]. We use recently derived results to provide an alternative proof of this result and to derive extensions.
