Time-Dependent Multi-Centre Solutions from New Metrics with Holonomy Sim(n-2)
G. W. Gibbons, C. N. Pope
The classifications of holonomy groups in Lorentzian and in Euclidean signature are quite different. A group of interest in Lorentzian signature in n dimensions is the maximal prop…
General Very Special Relativity is Finsler Geometry
G. W. Gibbons, Joaquim Gomis, C. N. Pope
We ask whether Cohen and Glashow's Very Special Relativity model for Lorentz violation might be modified, perhaps by quantum corrections, possibly producing a curved spacetime with…
Rotating Black Holes in Gauged Supergravities; Thermodynamics, Supersymmetric Limits, Topological Solitons and Time Machines
M. Cvetic, G. W. Gibbons, H. Lu +1
We study the thermodynamics of the recently-discovered non-extremal charged rotating black holes of gauged supergravities in five, seven and four dimensions, obtaining energies, an…
Phantom Matter and the Cosmological Constant
G. W. Gibbons
Motivated by some recent speculative attempts to model the dark energy, scalar fields with negative kinetic energy coupled to gravity without a cosmological constant are considered…
De Sitter Space from Warped Supergravity Solutions
G. W. Gibbons, C. M. Hull
The solutions of 10 and 11 dimensional supergravity that are warped products of de Sitter space with a non-compact `internal' space are investigated. A convenient form of the metri…
Embedding Branes in Flat Two-time Spaces
L. Andrianopoli, M. Derix, G. W. Gibbons +3
We show how non-near horizon, non-dilatonic -brane theories can be obtained from two embedding constraints in a flat higher dimensional space with 2 time directions. In particul…
