| Abstract: | Strong gravitation plane waves are represented in terms of the Maurer-Cartan spin connection coefficients in cosmological
background. It was shown that the diffeo-invariance of spin connection coefficients leaves only one degree of freedom of the
strong gravitation plane waves in contrast to the metric approach, where gravitation waves have two degrees of freedom like
photons in QED. The Hilbert action of gravitation waves in terms of spin connection coefficients takes the form of a bilinear
field theory. |
