相对论性DNLS与Kaup-Newell族

Relativistic DNLS and Kaup-Newell Hierarchy

Oktay K. Pashaev, Jyh-Hao Lee

摘要:

利用Kaup-Newell族的递推算子,构造了相对论导数NLS方程和相应的拉克斯对.在非相对论极限$c \rightarrow \infty$下,它化为DNLS方程,并在任何相对论修正阶下保持可积性。该方程的线性问题的紧凑的显式表示成为可能,由于概念的$q$ -演算有两个基地,其中之一是递归算子,另一个是谱参数。

英文摘要:

By the recursion operator of the Kaup-Newell hierarchy we construct the relativistic derivative NLS (RDNLS) equation and the corresponding Lax pair. In the nonrelativistic limit $c \rightarrow \infty$ it reduces to DNLS equation and preserves integrability at any order of relativistic corrections. The compact explicit representation of the linear problem for this equation becomes possible due to notions of the $q$-calculus with two bases, one of which is the recursion operator, and another one is the spectral parameter.
