Zur kugelsymmetrischen Vakuumlösung der TREDERschen Gravitationstheorie

Spherically symmetric vacuum solutions of TREDER'S gravitation theory are investigated and the problem of the gravitational collapse in this theory is discussed. It is shown that the surface r = a + b of the solution \documentclass{article}\pagestyle{empty}\begin{document}$ ds^2 \, = \, - \,\left({\frac{{r - a - b}}{{r - a}}} \right)^2 \,dt^2 \, + \,\frac{{r^2 }}{{(r - a)^2 }}dt^2 \, + \,r^2 \,(d\Theta ^2 \, + \,\sin ^2 \,\Theta d\varphi ^2) $\end{document} is an impermeable physical barrier.
