ABSTRACT
General relativity represents the physical framework to describe gravitational phenomena. One of its exciting and at the same time most disturbing features is the prediction of spacetime singularities, regions where the geometry becomes singular. In the standard approach to general relativity the singular regions are excluded from the physical spacetime manifold, since concepts such as curvature lose their classical meaning. Unfortunately, general relativity is an inherently non-linear theory, which is in sharp contrast to the linear distributional framework, and therefore puts an immediate stopgap to the applicability of distributional concepts. The Kerr-geometry represents the spacetime that is generated by a rotating black hole.
