Non-local symmetries of the Hirota-Satsuma coupled KdV system and their applications
Junchao Chen, Xiangpeng Xin, Yong Chen
The nonlocal symmetry is derived from the known Darboux transformation (DT) of the Hirota-Satsuma coupled KdV (HS-cKdV) system, and infinitely many nonlocal symmetries are obtained…

A systemic method to construct the high order nonlocal symmetries
Xiangpeng Xin, Yong Chen
We propose a systemic method of applying the auxiliary systems of original equations to find the high order nonlocal symmetries of nonlinear evolution equation. In order to validat…
