Query: Energy-Momentum Tensor Valued Distributions for the Schwarzschild and
  Reissner-Nordstrom Geometries   An approach to computing, withing the framework of distribution theory, the
distributional valued energy-momentum tensor for the Schwarzschild spacetime is
disscused. This approach avoids the problems associated with the regularization
of singularities in the curvature tensors and shares common features with the
by now standard treatment of discontinuities in General Relativity. Finally,
the Reissner-Nordstrom spacetime is also considered using the same approach.
