Twisted Cohomotopy implies M5-brane anomaly cancellation

18 Feb 2020 · Hisham Sati, Urs Schreiber ·

We highlight what seems to be a remaining subtlety in the argument for the cancellation of the total anomaly associated with the M5-brane in M-theory. Then we prove that this subtlety is resolved under the hypothesis that the C-field flux is charge-quantized in the generalized cohomology theory called J-twisted Cohomotopy.
