These equations allow to include “infinity” on a finite grid, solving regular equations, whose solutions give rise to solutions of the Einstei

The limit from the Einstein field equations in (d+1)-dimensional spacetime is applied to achieve well- defined mathematical expressions in 4-dimen

In particular, the type of signal the GW deposits in the detector in each case will be assessed, as well as its intensity and deconvolution. Brief reference will also be made to detector sensitivity characterisation, inclu

Nationale Feiertage und Feste der Türkeion for the shortest path in the bulk for a 1+4 cosmological metric. The time cost and the redshifts for photons and gravitons after travelling their respective path are compared. We consider some numerical solutions of the shortest path equation, and show that there is no shortest path in the bulk f

The evolution equations for Stokes parameters on a curved space-time are obtained using the parallel transport of the polarization vector along a null geodesic. The interest of these equations in Astrophysics and Relativistic Cosmology is outlined.
