A field theory representing a natural generalization of the theory of relativity is being
constructed by using a tetrad-space. A unique set of field equations exactly equal in number …

In the spring of 1946, Professor W. Pauli turned over to the author of this paper galleys of a
paper by P. Jordan entitled" Gravitationstheorie mit veriinderlicher Gravitationszahl", which …

The new field theory has been developed in two papers. The first, quoted as I, contains not
only a classical treatment, but also an attempt at quantization; the second, quoted as II, a …

In order to trace out with more understanding the consequences of general relativity it is
advantageous to have exact solutions of Einstein's field equations which show more detail …

In a recent paper Prof. A. Einstein has proposed equations determining a field containing
both gravitational and electromagnetic phenomena, the underlying geometry being of a type …

Every attempt to establish a unified-field theory must start, in my opinion, from a group of
transformations which is no less general than that of the continuous transformations of the …

The clearest logical characterization of the general theory of relativity can be stated as
follows: it is the theory which avoids the introduction of the" in-ertial system". It was Levi …

because this question of geometrical representation may be of interest, I offer this paper as a …

The four-dimensional geometry of th& three electromagnetic tensors (namely the six-vector
Fab, its dual F%,, and the energy tensor E&) has been studied by Rainich|, and more …

''N the following we shall give a new presentation of the generalized theory of gravitation,
which constitutes a certain progressin clarity as compared to the previous presentations.* It …
