An article that we have written:

• Twisted Cohomotopy implies M-Theory anomaly cancellation

$\,$

Abstract. We show that all the expected anomaly cancellations in M-theory follow from charge-quantizing the C-field in the non-abelian cohomology theory twisted cohomotopy. Specifically, we show that such cocycles exhibit all of the following:

1. the half-integral shifted flux quantization condition,
2. the cancellation of the total M5-brane anomaly,
3. the M2-brane tadpole cancellation,
4. the cancellation of the $W_7$ spacetime anomaly,
5. the C-field integral equation of motion,
6. the C-field background charge.

Along the way, we find that the calibrated $N =1$ exceptional geometries (${Spin}(7)$, $G_2$, ${SU}(3)$, ${SU}(2)$) are all induced from the classification of twists in Cohomotopy. Finally we show that the notable factor of $1/24$ in the anomaly polynomial reflects the order of the 3rd stable homotopy group of spheres.
