Camassa-Holm方程在孤波附近的解
摘要:
In this paper, solutions of the Camassa-Holm equation near the soliton is decomposed by pseudo-conformal transformation as follow: λ 1/2 (t)u(t,λ(t)y+x(t))=Q(y)+ε(t,y), and the residuals ε is estimated: |ε(t,y)| Ca 3T e -θ|y| +|λ 1/2 (t)ε 0|. We prove that the solution of the Cauchy problem and the soliton Q is sufficiently close as y→∞ ,and the approximation degree of the solution and Q is the same as that of initial data and Q if initial value and the soliton are close enough, besides the energy distribution of ε is consistent with the distribution of the soliton Q in H 2 .
