Group Reduction of Heterotic Supergravity
H. Lu, C. N. Pope, E. Sezgin
The reduction of ten-dimensional heterotic supergravity with Yang-Mills symmetry group K is performed on an arbitrary n-dimensional group manifold G. The reduction involves a nonva…
Consistent Pauli Sphere Reductions and the Action
H. Lu, C. N. Pope, K. S. Stelle
It is a commonly held belief that a consistent dimensional reduction ansatz can be equally well substituted into either the higher-dimensional equations of motion or the higher-dim…
Non-Extremal Rotating Black Holes in Five-Dimensional Gauged Supergravity
Z. W. Chong, M. Cvetic, H. Lu +1
Supersymmetric black holes in five-dimensional gauged supergravity must necessarily be rotating, and so in order to study the passage to black holes away from supersymmetry, it is…
General Kerr-NUT-AdS Metrics in All Dimensions
W. Chen, H. Lu, C. N. Pope
The Kerr-AdS metric in dimension D has cohomogeneity [D/2]; the metric components depend on the radial coordinate r and [D/2] latitude variables μ_i that are subject to the constra…
Resolutions of Cones over Einstein-Sasaki Spaces
H. Lu, C. N. Pope
Recently an explicit resolution of the Calabi-Yau cone over the inhomogeneous five-dimensional Einstein-Sasaki space Y^{2,1} was obtained. It was constructed by specialising the pa…
Separability in Cohomogeneity-2 Kerr-NUT-AdS Metrics
W. Chen, H. Lu, C. N. Pope
The remarkable and unexpected separability of the Hamilton-Jacobi and Klein-Gordon equations in the background of a rotating four-dimensional black hole played an important role in…
Kerr-de Sitter Black Holes with NUT Charges
W. Chen, H. Lu, C. N. Pope
The four-dimensional Kerr-de Sitter and Kerr-AdS black hole metrics have cohomogeneity 2, and they admit a generalisation in which an additional parameter characterising a NUT char…
