Omega vs. pi, and 6d anomaly cancellation

Abstract In this note we review the role of homotopy groups in determining non-perturbative (henceforth ‘global’) gauge anomalies, in light of recent progress understanding global anomalies using bordism. We explain why non-vanishing of π d (G) is neither a necessary nor a sufficient condition for t...
