D. Lyndenbell et al., CORRECTION TO GEOMETRIC EXTENSION THROUGH SCHWARZSCHILD R = 0, Monthly Notices of the Royal Astronomical Society, 262(2), 1993, pp. 325-326
A new method of giving meaning to Einstein's equations at the Schwarzs
child singularity is used to show that the extension proposed by Lynde
n-Bell & Katz is not empty at r = 0.
