The cosmological constant in the framework of gravito-magnetodynamic waves in weak gravitational fields (Q1424859)

The authors of this interesting paper show how the cosmological constant \(\Lambda \) interferes in the study of gravito-magnetodynamic wave propagation in weak gravitational fields. Einstein's equations for such fields can be linearized and written in a Maxwellian form. The type of waves, which are obtained here, as well as the associated phase velocities, is in a strong connection with the cosmological constant and its characteristics, such as its magnitude. The authors discuss an original approach and at the same time, they open a new direction of investigation in the theoretical and experimental study of an important and actual problem of contemporary cosmology.
