Equivariant Cohomotopy implies orientifold tadpole cancellation

17 Jun 2020 Sati Hisham Schreiber Urs

There are fundamental open problems in the precise global nature of RR-field tadpole cancellation conditions in string theory. Moreover, the non-perturbative lift as M5/MO5-anomaly cancellation in M-theory had been based on indirect plausibility arguments,lacking a microscopic underpinning in M-brane charge quantization...
