Hidden Spacetime Symmetries and Generalized Holonomy in M-theory
M. J. Duff, James T. Liu
In M-theory vacua with vanishing 4-form F, one can invoke the ordinary Riemannian holonomy H \subset SO(1,10) to account for unbroken supersymmetries n=1, 2, 3, 4, 6, 8, 16, 32. Ho…

Gauge Dyonic Strings and Their Global Limit
M. J. Duff, J. Liu, H. Lu +1
We show that six-dimensional supergravity coupled to tensor and Yang-Mills multiplets admits not one but two different theories as global limits, one of which was previously though…

Twenty Years of the Weyl Anomaly
M. J. Duff
In 1973 two Salam protégés (Derek Capper and the author) discovered that the conformal invariance under Weyl rescalings of the metric tensor d…
