Query: Noncommutative Reissner-Nordstr{\o}m Black hole   A deformed embedding of the Reissner-Nordstr{\o}m spacetime is constructed
within the framework of a noncommutative Riemannian geometry. We find
noncommutative corrections to the usual Riemannian expressions for the metric
and curvature tensors, which, in the case of the metric, are valid to all
orders in the deformation parameter. We calculate the area of the event horizon
of the corresponding noncommutative R-N black-hole, obtaining corrections up to
fourth order in the deformation parameter for the area of the black-hole.
Finally we include some comments on the noncommutative version on one of the
second order scalar invariants of the Riemann tensor, the so called Kretschmann
invariant, a quantity regularly used in order to extend gravity to quantum
level.
