标题： Consistent and covariant commutator anomalies in the chiral Schwinger model

摘要： 我们在费米子的正则量子化框架内推导出手征QED$_2$的所有协变且一致的散度和换位子异常。进一步地，我们计算了所有出现的算符的时间演化，并发现所有换位子都以规范的方式演化。我们还讨论了我们的结果与规范场空间中非平凡U(1)曲率发现之间的关系。 显示英文摘要

摘要： We derive all covariant and consistent divergence and commutator anomalies of chiral QED$_2$ within the framework of canonical quantization of the fermions. Further, we compute the time evolution of all occurring operators and find that all commutators evolve canonically. We comment on the relation of our results to the finding of a nontrivial U(1)-curvature in gauge-field space.
