摘要:

在四维中,'t Hooft 符号为描述瞬子物理中基础的自对偶结构提供了一个紧凑而强大的框架。将这一框架推广到六维时,六维 't Hooft 符号可以利用洛伦兹群 $Spin(6)$ 与酉群 $SU(4)$ 之间的同构来构造。我们证明,由厄米杨-米尔斯方程支配的六维自对偶结构可以用这些推广的 't Hooft 符号优雅地组织起来。我们还提出了一种系统方法,利用推广的 't Hooft 符号从六维流形上的自旋联络构造厄米杨-米尔斯瞬子。我们对瞬子数和欧拉数等拓扑不变量进行了深入分析。

英文摘要:

In four dimensions, 't Hooft symbols offer a compact and powerful framework for describing the self-dual structures fundamental to instanton physics. Extending this to six dimensions, the six-dimensional 't Hooft symbols can be constructed using the isomorphism between the Lorentz group $Spin(6)$ and the unitary group $SU(4)$. We demonstrate that the six-dimensional self-dual structures governed by the Hermitian Yang-Mills equations can be elegantly organized using these generalized 't Hooft symbols. We also present a systematic method for constructing Hermitian Yang-Mills instantons from spin connections on six-dimensional manifolds using the generalized 't Hooft symbols. We provide a thorough analysis of the topological invariants such as instanton and Euler numbers.
