Vc. Prasad et Pbl. Gaur, A NOTE ON THE GENERALIZED KATZENELSON METHOD FOR PIECEWISE-LINEAR RESISTIVE-NETWORKS, SIAM journal on mathematical analysis, 24(6), 1993, pp. 1662-1665
Ohtsuki, Fijisawa, and Kumagai [SIAM J. Math. Anal., 8 (1977), pp. 69-
99] proposed a generalisation of Katzenelson's method that is useful f
or a large class of piecewise linear resistive networks. In this note,
errors are pointed out and the correct proof is presented.
