关于一类Korteweg-de Vries型方程的Lie对称性和势对称性的几点注记

Some remarks about Lie and potential symmetries of a class of Korteweg-de Vries type equations

Oleksii Pliukhin, Danny Arrigo, Roman Cherniha

摘要:

给出了一类Korteweg-de Vries型方程的Lie对称性和势对称性的初步结果。为了证明势对称的存在性,分析了三种不同的所谓决定方程组。结果表明,两个系统只导致李对称,而第三个系统产生潜在的对称,只要方程有适当的结构

英文摘要:

Preliminary results about Lie and potential symmetries of a class of Korteweg-de Vries type equations are presented. In order to prove existence of potential symmetries three different systems of so called determining equations are analysed. It is shown that two systems lead only to Lie symmetries while the third system produces potential symmetries provided the equation in question has an appropriate structure
