T. Shirafuji et al., ENERGY OF GENERAL SPHERICALLY SYMMETRICAL SOLUTION IN THE TETRAD THEORY OF GRAVITATION, Progress of theoretical physics, 95(3), 1996, pp. 665-678
We find the most general spherically symmetric solution in a special c
lass of the tetrad theory of gravitation. The tetrad gives the Schwarz
schild metric. The energy is calculated using both the superpotential
method and the Euclidean continuation method. We find that unless the
time-space components of the tetrad go to zero faster than 1/root r at
infinity,the two methods give different results and that these result
s differ from the gravitational mass of the central gravitating body.
This fact implies that the time-space components of the tetrad describ
ing, an isolated spherical body must vanish faster than 1/root r at in
finity.
