Feldgleichungen der T REDER schen Gravitationstheorie, die aus einem Gravitationstheorem herleitbar sind. II

In the frame work of non‐linear generalizations of T REDER 's tetrad theory of gravitation considered in part I. a pure bimetric gravitation theory results for the L AGRANG ian Ω (1) F with ω 2 = 1. The discussion of the post‐N EWTON ian approximation given in I. has demonstrated that must be: ω 2 = −1 − 2ω 1 . ‐ However, a L AGRANG ian with ω 1 = − ω 2 = −1 is identical with G UPTA 's post‐N EWTON ian approximation for E INSTEIN 's general relativistic L AGRANG ian. Therefore, for ω 1 = − ω 2 = − 1 the E INSTEIN effects are resulting evidently and the question discussed in I. the tetrad formalism becomes non‐important.
