Titre | U-duality Anomaly Cancelation |
Résumé | Theories of quantum gravity are believed to have no global symmetries. We will check this conjecture for the U-duality symmetry in 4d N=8 supergravity. Since this theory arises from string theory, the 't Hooft anomaly for this symmetry ought to vanish. We then perform a bordism computation to classify the anomaly of U-duality and notice an interesting fact about the particular Thom spectrum that we use for the computation. Finally we show that evaluating the anomaly for our particular theory on the generating manifold of the bordism group leads to it vanishing. |
