anomaly相互作用的代数

The algebra of anomaly interplay

Joe Davighi, Nakarin Lohitsiri

摘要:

我们给出了一个一般性的描述,可以发生在本地和全球异常之间的相互作用,(共)bordism。在数学上,这种相互作用被编码在已知用于对可逆场论进行分类的短精确序列的非正则分裂中。我们研究的现象在2,4和6维的各种例子。我们还描述了如何理解异常的相互作用提供了一个严格的基于边界的版本的旧方法计算全球异常(从当地异常的相关理论)由于埃利祖尔和奈尔。

英文摘要:

We give a general description of the interplay that can occur between local and global anomalies, in terms of (co)bordism. Mathematically, such an interplay is encoded in the non-canonical splitting of short exact sequences known to classify invertible field theories. We study various examples of the phenomenon in 2, 4, and 6 dimensions. We also describe how this understanding of anomaly interplay provides a rigorous bordism-based version of an old method for calculating global anomalies (starting from local anomalies in a related theory) due to Elitzur and Nair.
