摘要

基于Lenard梯度序列，得到了非局部非线性Schrödinger (NNLS)方程的层次结构。利用Lax表示，给出了具有Lie-Poisson结构的有限维非局部可积系统。然后在坐标变换下，将具有Lie-Poisson结构的非局部有限维可积系统表示为标准辛结构的正则哈密顿系统。此外，构造了NNLS方程和非局部复修正Korteweg-de Vries (NcmKdV)方程的参数表示。最后，根据Hamilton-Jacobi理论，建立了作用角变量，并讨论了Lie-Poisson hamilton系统的反演问题。

A nonlocal finite-dimensional integrable system related to the nonlocal nonlinear Schrodinger equation hierarchy

Based on the Lenard gradient sequence, a hierarchy of the nonlocal nonlinear Schrödinger (NNLS) equations is obtained. Using the Lax representation, the nonlocal finite-dimensional integrable system with Lie–Poisson structure is presented. Then, under coordinate transformation, the nonlocal finite-dimensional integrable system with Lie–Poisson structure can be expressed as the canonical Hamiltonian system of the standard symplectic structures. Moreover, the parametric representation of the NNLS equation and the nonlocal complex modified Korteweg–de Vries (NcmKdV) equation are constructed. Finally, according to the Hamilton–Jacobi theory, the action–angle variables are built and the inversion problem related to the Lie–Poisson Hamiltonian systems is discussed.
