Abstract: In this class, we finish the discussion about global anomalies, discussing global anomalies in topological superconductors. Interestingly, the studies of global anomalies in these materials show a different topological invariant from the Altland-Zirnbauer classification. To understand why, we consider the effect of interactions in topological superconductors, showing that the presence of interactions that respect the symmetry can change the topological class, but this is encoded correctly in the anomalies. Further, we discuss the change of the partition functions when using different frames to describe a Chern-Simons term, what gives rise to the framing anomaly.
