A. Lasota et J. Traple, An application of the Kantorovich-Rubinstein maximum principle in the theory of the Tjon-Wu equation, J DIFF EQUA, 159(2), 1999, pp. 578-596
A new proof of the asymptotic stability of a stationary solution of the Tjo
n-Wu equation is given. The proof is based on some special properties (the
maximum principle) of the Kantorovich-Rubinstein metric. Our method allows
us to consider the Tjon-Wu equation in a more general form. (C) 1999 Academ
