标题： 't Hooft Anomaly Matching Conditions for Generalized Symmetries in 2D

摘要： 't Hooft 异常匹配条件是研究和检验量子场论中非微扰问题的标准工具。 我们给出了二维庞加莱不变理论中异常匹配条件的一个新的简单证明。 我们考虑了一类广义对称性下的不变性情况，这类对称性包括交换和非交换内部对称性、由应力张量生成的时空对称性以及由高自旋流生成的 W 型对称性。 显示英文摘要

摘要： The 't Hooft anomaly matching conditions are a standard tool to study and test non-perturbative issues in quantum field theory. We give a new, simple proof of the anomaly matching conditions in 2D Poincare` invariant theories. We consider the case of invariance under a large class of generalized symmetries, which include abelian and non-abelian internal symmetries, space-time symmetries generated by the stress tensor, and W-type of symmetries generated by higher spin currents.
