从带负幂次谱参数的谱问题出发,构造了一类广义自对偶Yang-Mills方程.这类方程包括若干著名的Lax可积方程,如Takasaki情形、Belavin-Zakharov情形、AblowitzChakravarty-Takhtajall情形和Ma情形.进而建立了这类方程的达布变换的精确表达式.

We know that the self-dual Yang-Mills (SDYM) equation has infinitely manysymmetries, and these symmtries constitute an infinite dimensional Lie algebra.This property is commonly shared by almost all the 1+l-dimensional integrableevolution equations (soliton equations), and has become a very important criterion ofintegrability for the evolution equations. So in a sense the SDYM equation is integr-able. In recent years people have found that some typical soliton equations, such 展开更多

The self-dual Yang-Mills equation is considered, and by using the corresponding linear system and the infinitesimal version of the ’dressing method’ infinite numbers of symmetries of the self-dual Yang-Mills equation are obtained. The set of these symmetries form into two subsets, which constitute a loop algebra and Virasoro algebra respectively. 展开更多
