Two time-dependent mass profiles are proposed as exact models of the last stage of Schwarzschild collapse; one develops the curvature singularity immediately, the other only at infinite time, though the second model's formulas are internally inconsistent.

abstract
Using the Kerr-Schild decomposition of the metric tensor that employs the algebraically special nature of the Kerr-Newman space-time family, we calculate the energy-momentum tensor. The latter turns out to be a well-defined tensor-distribution with disk-like support.
