关于发展方程的非局部对称性、非局部守恒律和非局部变换

On nonlocal symmetries, nonlocal conservation laws and nonlocal transformations of evolution equations

Norbert Euler, Marianna Euler

摘要:

我们讨论了非局部对称性和非局部守恒律,遵循系统的潜在的发展方程。这些是辅助系统的李点对称性,也称为势对称性。我们定义了更高程度的潜在的对称性,然后导致非局部守恒律和非局部变换的方程。我们证明了我们的方法由汉堡的层次结构和Calogero-Degasperis-Algimov-Shabat层次结构。

英文摘要:

We discuss nonlocal symmetries and nonlocal conservation laws that follow from the systematic potentialisation of evolution equations. Those are the Lie point symmetries of the auxiliary systems, also known as potential symmetries. We define higher-degree potential symmetries which then lead to nonlocal conservation laws and nonlocal transformations for the equations. We demonstrate our approach by the Burgers' hierarchy and the Calogero-Degasperis-Ibragimov-Shabat hierarchy.
