[Multi-soliton-type solutions of the generalized KdV equations]
We consider the generalized Korteweg–de Vries equations in the subcritical and critical cases. Let Rj(t,x)=Qcj(x−cjt−xj) be N soliton solutions of this equation, with corresponding speeds 0<c1<c2<⋯<cN. In this Note, we give a sketch of the proof of the following result. Given , there exists one and only one solution ϕ of the generalized KdV equation such that ‖ϕ(t)−∑Rj(t)‖H1→0 as t→+∞. Complete proofs will appear later.
On considère les équations de Korteweg–de Vries généralisées dans les cas sous-critique et critique. Soit solutions de type solitons de l'équation, correspondant à des vitesses 0<c1<c2<⋯<cN. Dans cette Note, on donne les idées principales de la démonstration du résultat suivant. Etant donnés , il existe une et une seule solution ϕ de l'équation de KdV généralisée telle que ‖ϕ(t)−∑Rj(t)‖H1→0 quand t→+∞. Les preuves complètes seront publiées plus tard.
