Geometric and topological structures related to M-branes
The actions, anomalies, and quantization conditions allow the M2-brane and the M5-brane to support, in a natural way, structures beyond Spin on their worldvolumes.The main examples are twisted String structures.This also extends to twisted String c structures, which we introduce and relate to twisted String structures.The relation of the C-field …
