摘要
我们考虑环面上的纯拓扑 d Yang-Mills 理论,其拉格朗日量中加入了以 -项形式出现的第二 Stiefel-Whitney 类。将证明,在 时存在一类 ()规范理论,具有二重简并真空,并自发破缺时间反演与电荷共轭对称性。相应的序参量由 一形式对称的生成元 给出。

备注
The ambiguity between the second Stiefel-Whitney class $w_2$ and an invariant of $PSU(N)$ bundles $u_2$ was removed. Conclusion section and more references were added in version 3
