双微分演算与可积模型

Bi-differential calculi and integrable models

Aristophanes Dimakis, Folkert Muller-Hoissen

摘要:

在完全可积的经典模型,包括手征和户田模型以及KP和自对偶杨-米尔斯方程的守恒电流的存在的一个无限集,追溯到一个简单的建设的无限链的封闭(分别,协变常数)1-形式(规范)双微分。后者包括一个微分代数上的两个微分映射的行为。在一个规范的双微分,这些映射扩展到平坦的协变导数。

英文摘要:

The existence of an infinite set of conserved currents in completely integrable classical models, including chiral and Toda models as well as the KP and self-dual Yang-Mills equations, is traced back to a simple construction of an infinite chain of closed (respectively, covariantly constant) 1-forms in a (gauged) bi-differential calculus. The latter consists of a differential algebra on which two differential maps act. In a gauged bi-differential calculus these maps are extended to flat covariant derivatives.
