DISTRIBUTIONAL ENERGY-MOMENTUM TENSOR OF THE EXTENDED KERR GEOMETRY

We generalize previous work on the energy-momentum tensor distribution of the Kerr geometry by extending the manifold structure into the neg ative mass region. Since the extension of the flat part of the Kerr-Sc hild decomposition from one sheet to the double cover develops a singu larity at the branch surface, we have to take its non-smoothness into account. It is, however, possible to find a geometry within the genera lized Kerr-Schild class that is, in the Colombeau sense, associated to the maximally analytic Kerr metric.
