本文利用最陡下降法研究了非线性短脉冲方程uxt = u+16(u3)xx,u(x,0)= u 0(x)∈ H(R)的Cauchy问题,其中H(R)= W3,1(R)<$H2,2(R)是加权Sobolev空间.在新的尺度(y,t)下,利用Riemann-Hilbert问题的解构造了短脉冲方程的解。在任何固定的时空锥C中(y1,y2,v1,v2)={(y,t)∈ R2:y= y 0+ vt,y 0∈[y1,y2],v∈[v1,v2]},我们计算了解u(x,t)的长时间渐近展开式,这意味着孤子分解猜想由三项组成:第一阶项可以用一个N(I)-孤子来表征,它的参数在通过圆锥时受到局域孤子-孤子相互作用的调制,第二阶项可以用一个N(I)-孤子来表征,|不|-1/2阶项来自连续光谱上的孤子-辐射相互作用,直到残余误差阶O(|不|(1)从一个简单的方程。我们的结果还表明,孤子解的短脉冲方程是渐近稳定的。
In this paper, we apply∂‾ steepest descent method to study the Cauchy problem for the nonlinear short-pulse equation u x t= u+ 1 6 (u 3) x x, u (x, 0)= u 0 (x)∈ H (R), where H (R)= W 3, 1 (R)∩ H 2, 2 (R) is a weighted Sobolev space. The solution of the short-pulse equation is constructed via a solution of Riemann-Hilbert problem in the new scale (y, t). In any fixed space-time cone C (y 1, y 2, v 1, v 2)={(y, t)∈ R 2: y= y 0+ v t, y 0∈[y 1, y 2], v∈[v 1, v 2]}, we compute the long time asymptotic expansion of the solution u (x, t), which implies soliton resolution conjecture consisting of three terms: the leading order term can be characterized with an N (I)-soliton whose parameters are modulated by a sum of localized soliton-soliton interactions as one moves through the cone; the second| t|− 1/2 order term coming from soliton-radiation interactions on continuous spectrum up to an residual error order O (| t|− 1) from a∂‾ equation. Our results also show that soliton solutions of the short-pulse equation are asymptotically stable.
