Classical General Relativity in more than four spacetime
dimensions has been the subject of increasing attention in
recent years. Among the reasons why it should be interesting to
study this extension of Einstein’s theory, and in particular its
black hole solutions, we may mention that - String theory
contains gravity and requires more than four dimensions. In
fact, the first successful statistical counting of black hole
entropy in string theory was performed for a fivedimensional
black hole. This example provides the best laboratory for the
microscopic string theory of black holes. - The AdS/CFT
correspondence relates the properties of a d-dimensional black
hole with those of a quantum field theory in d − 1 dimensions. -
The production of higher-dimensional black holes in future
colliders becomes a conceivable possibility in scenarios
involving large extra dimensions and TeV-scale gravity. - As
mathematical objects, black hole spacetimes are among the most
important Lorentzian Ricci-flat manifolds in any dim
