Relativistic DNLS and Kaup-Newell hierarchy
(Institute of Mathematics, 2017-07)
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 → ∞ it reduces to DNLS equation and preserves ...
