论文摘要
异常是限制超出标准模型的理论的非常强大的工具。我们对一些主题进行了教学概述，说明了时空异常在弦理论中所扮演的重要作用。在讨论了量子场理论中取消异常的一般问题之后，重点是通过绿色 - 史瓦尔茨机制在类型I字符串理论中取消异常的重点。还审查了异常流入的概念，及其在评估D-Brane异常耦合的评估中。最后，我们简要评论了有关类别理论语言反复的最新发展。
Anomalies are a very powerful tool in constraining theories beyond the standard model. We give a pedagogical overview of some topics illustrating the important role played by spacetime anomalies in string theory. After discussing the general problem of anomaly cancellation in quantum field theory, the focus is set on the cancellation of anomalies in type-I string theory through the Green-Schwarz mechanism. The notion of anomaly inflow is also reviewed, as well as its application to the evaluation of D-brane anomalous couplings. Finally, we briefly comment on recent developments concerning the reformulation of anomalies in the language of category theory.
