Alternative Gravitational Theories in Four Dimensions
Friedrich W. Hehl
We argue that from the point of view of gauge theory and of an appropriate interpretation of the interferometer experiments with matter waves in a gravitational field, the Einstein…
Is a `hadronic' shear current one of the sources in metric-affine gravity?
Friedrich W. Hehl, Yuri N. Obukhov
The Minkowski space of special relativity can be understood as a flat 4-dimensional affine space enriched by a constant Minkowski metric. If we gauge the general affine group and `…
A note on post-Riemannian structures of spacetime
Friedrich W. Hehl, Uwe Muench
A four-dimensional differentiable manifold is given with an arbitrary linear connection . Megged has claimed that he can define a metric by means of a…
On the rotation of the universe
Yuri N. Obukhov, Vladimir A. Korotky, Friedrich W. Hehl
We point on a different possible explanation of the observations reported recently by Nodland and Ralston, PRL 78 (1997) 3043 [astro-ph/9704196]. The dipole anisotropy of the polar…
Irreducible decompositions in metric-affine gravity models
Yu. N. Obukhov, E. J. Vlachynsky, W. Esser +1
The irreducible decomposition technique is applied to the study of classical models of metric-affine gravity (MAG). The dynamics of the gravitational field is described by a 12-par…
Stress and Hyperstress as Fundamental Concepts in Continuum Mechanics and in Relativistic Field Theory
Frank Gronwald, Friedrich W. Hehl
The notions of stress and hyperstress are anchored in 3-dimensional continuum mechanics. Within the framework of the 4-dimensional spacetime continuum, stress and hyperstress trans…
