M 理论五膜的异常消除需要引入“凹凸形式”来平滑五膜源。我们在 3 + 1 维轴子弦的更简单情况下讨论了这种凹凸形式的物理起源，并根据费米子零模式的径向轮廓构建它。当异常被大量流入抵消时，我们的处理可以更清楚地理解协变而不是一致异常所扮演的角色。我们简要讨论了这些结果对 M 理论中五膜异常的推广。
Anomaly cancellation for M-theory five-branes requires the introduction of a ``bump-form' which smoothes out the five-brane source. We discuss the physical origin of this bump-form in the simpler case of axion strings in 3 + 1 dimensions and construct it in terms of the radial profile of the fermion zero modes. Our treatment allows for a clearer understanding of the role played by covariant rather than consistent anomalies when anomalies are canceled by inflow from the bulk. We briefly discuss the generalization of these results to five-brane anomalies in M-theory.
