Matrix Cosmology
Daniel Z. Freedman, Gary W. Gibbons, Martin Schnabl
Some speculative preliminary ideas relating matrix theory and cosmology are discussed.
On the stability of naked singularities
Gary W. Gibbons, Sean A. Hartnoll, Akihiro Ishibashi
We study the linearised stability of the nakedly singular negative mass Schwarzschild solution against gravitational perturbations. There is a one parameter family of possible boun…
Properties of some five dimensional Einstein metrics
Gary W. Gibbons, Sean A. Hartnoll, Yukinori Yasui
The volumes, spectra and geodesics of a recently constructed infinite family of five-dimensional inhomogeneous Einstein metrics on the two bundles over are examined. Th…
The General Kerr-de Sitter Metrics in All Dimensions
G. W. Gibbons, H. Lu, D. N. Page +1
We give the general Kerr-de Sitter metric in arbitrary spacetime dimension D\ge 4, with the maximal number [(D-1)/2] of independent rotation parameters. We obtain the metric in Ker…
Topology and Signature Changes in Braneworlds
Gary W. Gibbons, Akihiro Ishibashi
It has been believed that topology and signature change of the universe can only happen accompanied by singularities, in classical, or instantons, in quantum, gravity. In this note…
