Comments on “finite time stability with respect to time-varying sets”

Addendum Comments on “Finite Time Stability with Respect to Time-varying Sets” by L. LAM and L. WEISS, Vol. 298, Nos. 5 and 6, pp. 415421, Dec. 1974

In the above-mentioned article published in this Journal, Lam and Weiss reference a paper by Heinen and Wu* which unfortunately was not accepted for publication, and hence never appeared. Modifications and extensions of that work, however, have since been published (l)-(4).
