Gino Biondini, Jonathan Lottes, Dionyssis Mantzavinos

摘要:

对一类在无穷远渐近行为由反向传播波组成的初始条件,给出了聚焦非线性薛定谔方程的逆散射变换.该制剂考虑到分支性质的两个渐近特征值的相关散射问题。Jost本征函数和散射系数被明确定义为单值函数的复平面上的跳跃不连续沿某些分支切割。分析性质,对称性,离散谱,渐近性和行为的分支点明确讨论。反问题被表述为一个具有极点的矩阵Riemann-Hilbert问题。减少以前在文献中讨论的所有情况下,明确讨论。与物理相关的黎曼问题组成的几个特殊情况下的散射数据显式计算。

英文摘要:

The inverse scattering transform for the focusing nonlinear Schrodinger equation is presented for a general class of initial conditions whose asymptotic behavior at infinity consists of counterpropagating waves. The formulation takes into account the branched nature of the two asymptotic eigenvalues of the associated scattering problem. The Jost eigenfunctions and scattering coefficients are defined explicitly as single-valued functions on the complex plane with jump discontinuities along certain branch cuts. The analyticity properties, symmetries, discrete spectrum, asymptotics and behavior at the branch points are discussed explicitly. The inverse problem is formulated as a matrix Riemann-Hilbert problem with poles. Reductions to all cases previously discussed in the literature are explicitly discussed. The scattering data associated to a few special cases consisting of physically relevant Riemann problems are explicitly computed.
