Backlund-Transformation-Related Recursion Operators: Application to the Self-Dual Yang-Mills Equation

C. J. Papachristou, B. Kent Harrison

AI总结:

以自对偶Yang-Mills方程为例,研究通过非自洽Backlund变换关联的两个偏微分方程的对称性与递推算子,证明李代数同构并构造递推算子,进而揭示势对称性的李代数结构。

摘要:

以自对偶Yang-Mills(SDYM)方程为例,我们研究了一种关联两个由非自洽Backlund变换连接的偏微分方程的对称性和递推算子的方法。我们证明了SDYM方程的对称性与势SDYM(PSDYM)方程的对称性之间的李代数同构,并描述了这两个系统的递推算子的构造。利用PSDYM对称代数的某些已知方面,我们得出了关于SDYM方程“势对称性”的李代数结构的结论。

英文摘要:

By using the self-dual Yang-Mills (SDYM) equation as an example, we study a method for relating symmetries and recursion operators of two partial differential equations connected to each other by a non-auto-Backlund transformation. We prove the Lie-algebra isomorphism between the symmetries of the SDYM equation and those of the potential SDYM (PSDYM) equation, and we describe the construction of the recursion operators for these two systems. Using certain known aspects of the PSDYM symmetry algebra, we draw conclusions regarding the Lie algebraic structure of the "potential symmetries" of the SDYM equation.
