双微分与KdV方程

Bi-differential calculus and the KdV equation

Aristophanes Dimakis, Folkert Muller-Hoissen

摘要:

结合(不一定是交换)代数A上的规范双微分是N-分次左A-模,具有作用于其上的两个协变导数,作为某些(例如,非线性微分方程是平坦的和反对易的。因此,有一个迭代的广义守恒电流的建设。我们关联的规范双微分与Korteweg-de-Vries方程,并用它来计算守恒密度的这个方程。

英文摘要:

A gauged bi-differential calculus over an associative (and not necessarily commutative) algebra A is an N-graded left A-module with two covariant derivatives acting on it which, as a consequence of certain (e.g., nonlinear differential) equations, are flat and anticommute. As a consequence, there is an iterative construction of generalized conserved currents. We associate a gauged bi-differential calculus with the Korteweg-de-Vries equation and use it to compute conserved densities of this equation.
