异常安全离散群

Anomaly-safe discrete groups

Mu-Chun Chen, Maximilian Fallbacher, Michael Ratz, Andreas Trautner, Patrick K. S. Vaudrevange

摘要:

我们证明了存在一类有限群,即所谓的完美群,它不能表现出异常。这意味着所有非阿贝尔有限单群都是无异常群。另一方面,非完美群一般都有异常。我们提出了两种不同的方式,让一个理解这些声明。

英文摘要:

We show that there is a class of finite groups, the so-called perfect groups, which cannot exhibit anomalies. This implies that all non-Abelian finite simple groups are anomaly-free. On the other hand, non-perfect groups generically suffer from anomalies. We present two different ways that allow one to understand these statements.
