Abstract

We prove that the local L2 norm of the solution of the generalized Korteweg-de Vries equation

$$u_t + (F(u) + \sum\limits_{s = 0}^m {( - 1)^s D_x^{2s} u)_x = 0,m \geqslant 2,} $$

with nice initial datum, where F satisfies certain general conditions, for example, P(u) = up, where p is an odd integer ≧3, decays t o zero as time goes to infinity.
