立方格上的差分离散联络与曲率

Difference Discrete Connection and Curvature on Cubic Lattice

Ke Wu, Wei-Zhong Zhao, Han-Ying Guo

摘要:

以类似于连续情形的形式,我们以不同但等价的方式定义了正则格上离散向量丛上的差离散联络和曲率。我们基于格上的微分学将差分算子作为导数的离散对应物来处理。其中一个定义可以推广到随机格上的情形。讨论了我们的方法与格点规范理论的关系,并将其应用于离散可积系统。

英文摘要:

In a way similar to the continuous case formally, we define in different but equivalent manners the difference discrete connection and curvature on discrete vector bundle over the regular lattice as base space. We deal with the difference operators as the discrete counterparts of the derivatives based upon the differential calculus on the lattice. One of the definitions can be extended to the case over the random lattice. We also discuss the relation between our approach and the lattice gauge theory and apply to the discrete integrable systems.
