[期刊论文] 作者:Jian-wen Wu,Yue-jin Cai,Ji Lin, 来源:理论物理通讯:英文版 年份:2021
The nonlocal symmetry of the Sawada–Kotera(SK)equation is constructed with the known Lax pair.By introducing suitable and simple auxiliary variables,the nonlocal symmetry is localized and the finite transformation and some new solutions ar......

With the aid of the Painlevé analysis,we obtain residual symmetries for a new(3+1)-dimensional generalized Kadomtsev-Petviashvili(gKP)equation.The residual symmetry is localized and the finite transformation is proposed by introducing suit......
