On Schwarzschild's Topology in Brane-Worlds
The topological structure of Schwarzschild's space-time and its maximal
analytic extension are investigated in context of brane-worlds. Using the
embedding coordinates, these geometries are seen as different states of the
evolution of a single brane-world. Comparing the topologies and the embeddings
it is shown that this evolution must be followed by a signature change in the
bulk.Comment: 6 page
On the Stability of Black Holes at the LHC
The eventual production of mini black holes by proton-proton collisions at
the LHC is predicted by theories with large extra dimensions resolvable at the
Tev scale of energies. It is expected that these black holes evaporate shortly
after its production as a consequence of the Hawking radiation. We show that
for theories based on the ADS/CFT correspondence, the produced black holes may
have an unstable horizon, which grows proportionally to the square of the
distance to the collision point.Comment: 3 page
