关于KdV方程不适定性的一个注记

A note on ill-posedness for the KdV equation

Luc Molinet

摘要:

证明了KdV方程的解映射$ u_0 \mapsto u $在$ s<-1 $的$ H^s(\R) $中不能连续扩张.主要成分是著名的加藤平滑效应的mKdV方程以及三浦变换。

英文摘要:

We prove that the solution-map $ u_0 \mapsto u $ associated with the KdV equation cannot be continuously extended in $ H^s(\R) $ for $ s<-1 $. The main ingredients are the well-known Kato smoothing effect for the mKdV equation as well as the Miura transform.
