Bk. Shivamoggi et Dk. Rollins, THE PAINLEVE FORMULATIONS AND EXACT-SOLUTIONS OF THE NONLINEAR EVOLUTION-EQUATIONS FOR MODULATED GRAVITY-WAVE TRAINS, Journal of mathematical physics, 35(9), 1994, pp. 4779-4798
In this article the integrability aspects of the nonlinear evolution e
quations for modulated gravity wave trains are investigated by demandi
ng the Painleve property of the solutions. The Painleve formulations a
lso lead to kink-shaped exact localized solutions of these equations.
