The Cobordism Conjecture for the non-supersymmetric Spin(32)/Z_2 heterotic string
Consider the bordism class represented by $S^8$ with the map to $B\mathrm{String}$ given by a generator of $[S^8,B\mathrm{String}]=\pi_8(B\mathrm{String})\cong\mathbb{Z}$ , together…

Witten's conjecture on invariant partition functions and anomaly cancellation
An anomaly is a global anomaly in dimension $3$ , and an invariant partition function is a partition function unchanged by the relevant symmetry. Witten's conjecture. The existence…
