Ultraspinning instability of anti-de Sitter black holes
Ultraspinning instability anti-de Sitter
2010/12/23
Myers-Perry black holes with a single spin in d>5 have been shown to be unstable if rotating sufficiently rapidly. We extend the numerical analysis which allowed for that result to the asymptotically ...
Instability of the planetary orbits for space-time dimensions higher than four
Instability planetary orbits space-time dimensions
2010/12/20
It is shown that in a Minkowski space of total space-time dimension D = d + 1, the orbits of the planetary motion are stable only if the total dimension of space-time is D 4. The proof is performed ...

Myers-Perry black holes with a single spin in d > 5 have been shown to be unstable if
rotating suciently rapidly. We extend the numerical analysis which allowed for that result

Gravitational instability of the inner static region of a Reissner-Nordstrom black hole
Gravitational instability black hole inner static region
2010/3/17
Reissner--Nordstr\"om black holes have two static regions: $r > \ro$ and $0 < r < \ri$, where $0 < \ri < \ro$ are the inner and outer horizon radii. The stability of the exterior static region has bee...
On the instability of Reissner-Nordstrom black holes in de Sitter backgrounds
black holes instability Sitter backgrounds
2010/3/17
Recent numerical investigations have uncovered a surprising result: Reissner-Nordstrom-de Sitter black holes are unstable for spacetime dimensions larger than 6. Here we prove the existence of such in...
